It's no surprise that two players who helped Fantasy managers win the most this past season were Cooper Kupp and Deebo Samuel. They were both amazing and came at fantastic value in 2021.

Kupp and Samuel were two of the top three receivers this past season in PPR. Kupp, who was drafted toward the end of Round 4 based on his Average Draft Position on CBS Sports, averaged 25.9 PPR points per game, which was No. 1 at his position. Samuel, who was the steal of most drafts in 2021 with an ADP of Round 9, averaged 21.3 PPR points per game. He was the No. 3 receiver, slightly behind Davante Adams (21.5).

We know they helped many of you win Fantasy championships, and the data shows they helped many of you succeed in the regular season as well. And that's what we're looking at here.

This is the win percentage data on CBS Sports leagues for 2021. It is based on players rostered in 60 percent or more of leagues on CBS Sports, which came to about 150 players when factoring in kickers and DSTs, and shows total wins and not Fantasy titles. Only commissioner leagues were considered with at least eight Fantasy teams or more.

Not all of these players were actually in starting Fantasy lineups for most of the season. For example, the No. 1 running back based on win percentage was Chargers running back Justin Jackson. Remember, in Week 16, he took over for Austin Ekeler, who was sidelined due to COVID-19 protocols, and Jackson had 162 total yards and two touchdowns.

Jackson was likely added to many successful Fantasy rosters during the playoffs, which helped his win percentage. And the same could be said of other free agents like Ronald Jones, Amon-Ra St. Brown, Rashaad Penny, Jeff Wilson, Cordarrelle Patterson and K.J. Osborn. Those players weren't drafted in the majority of leagues, but they were among the top 25 overall players in win percentage.

As always, playing the waiver wire is the key to a successful season. But you have to hit on the right draft picks as well at great values -- like Kupp and Samuel, among others.

Now, let's examine the best players based on win percentage on CBS Sports leagues in 2021. We removed kickers and DSTs from this data, but here is how the other positions finished this past year. 

Quarterbacks

1. Tom Brady 0.550
2. Matthew Stafford 0.538
3. Josh Allen 0.537
4. Justin Herbert 0.537
5. Taysom Hill 0.522
6. Joe Burrow 0.511
7. Aaron Rodgers 0.510
8. Jalen Hurts 0.508
9. Dak Prescott 0.506
10. Patrick Mahomes 0.497
11. Tua Tagovailoa 0.495
12. Kirk Cousins 0.494
13. Kyler Murray 0.494
14. Jimmy Garoppolo 0.487
15. Derek Carr 0.484
16. Carson Wentz 0.483
17. Russell Wilson 0.473
18. Matt Ryan 0.472
19. Lamar Jackson 0.469
20. Ryan Tannehill 0.465

Brady was the No. 9 quarterback based on ADP, and he was amazing in his final year in the NFL. He led the league in passing yards (5,316) and passing touchdowns (43) and was the No. 3 Fantasy quarterback behind only Allen and Mahomes.

Stafford was also an incredible value as the No. 11 quarterback based on ADP, but Hill helped many Fantasy managers as a free agent when he took over for the Saints as the starter in Week 13. Even though he didn't close the season strong, he still helped many Fantasy managers reach the playoffs with 24 Fantasy points in Week 13 and 26 points in Week 14.

Only nine quarterbacks had a positive win percentage in 2021, and guys like Mahomes, Murray, Wilson and Jackson ended up as disappointments. That doesn't mean all of them failed or were busts, but those quarterbacks didn't enhance their Fantasy rosters.

Jackson was clearly the biggest letdown based on his ADP as the No. 3 quarterback off the board. Now, part of that is because of the ankle injury he sustained in Week 14, which eventually ended his season. Fantasy managers kept him on their rosters, but they had to scramble to find a replacement, which likely proved unsuccessful in most cases.

45. James Robinson 0.468
46. Myles Gaskin 0.465
47. Mike Davis 0.451

McCaffrey doesn't have a win percentage here because his roster percentage was 40 percent at the end of the season. He was dropped in most seasonal leagues after being placed on injured reserve following his ankle injury in Week 12.

Henry's roster percentage stayed at 70 percent despite his foot injury in Week 8. Many Fantasy managers hoped he would return during the regular season, but that didn't happen. Still, he helped contribute to a successful win percentage for many rosters.

The players who delivered based on their ADP were Taylor, Ekeler, Mixon and Harris. All four of them were drafted in the first two rounds, and they clearly helped many Fantasy managers in 2021 based on their win percentage.

Conversely, some of the biggest disappointments in 2021 were Cook, Gibson and Barkley. That trio was also drafted in the first two rounds, but they didn't help enough rosters to successful campaigns. Barkley was among the biggest busts last season with his production as well, averaging just 11.5 PPR points per game.

49. Emmanuel Sanders 0.445
50. DeAndre Hopkins 0.431

Like Kupp and Samuel, Chase was among the best value picks this past season. He was drafted in Round 7 based on ADP, and he finished as the No. 5 PPR receiver in points per game at 21.6.

But Chase wasn't the best rookie based on win percentage. That honor went to St. Brown, who was a star to close the season, scoring at least 15 PPR points in each of his final six games. I liked St. Brown as an under-the-radar rookie coming into 2021, but I never expected him to play like that for such a significant stretch. It's going to be fascinating to see how Fantasy managers treat St. Brown in 2022, and I like him as a No. 2 receiver worth drafting in Round 5 -- for now.

One of the bigger surprises on this list is Lamb, who happened to be on many productive Fantasy teams based on his win percentage. But he did not play well down the stretch of the season. It felt like the Cowboys forgot about Lamb when he had five targets or less in his final three games in a row, and he also failed to score a touchdown after Week 10. Hopefully, Dak Prescott and offensive coordinator Kellen Moore feed Lamb more often in 2022. 

Hopkins was the biggest disappointment on this list based on his ADP, which was Round 2 in most leagues. He missed seven games, including the final four with a knee injury, but many Fantasy managers held onto him with the hope he would return at the end of the year. That didn't happen, and Fantasy managers likely struggled to replace him.

Tight ends

1. Mark Andrews 0.549
2. Dawson Knox 0.520
3. Travis Kelce 0.517
4. George Kittle 0.516
5. Rob Gronkowski 0.516
6. Dallas Goedert 0.510
7. Dalton Schultz 0.507
8. Hunter Henry 0.503
9. Pat Freiermuth 0.502
10. Mike Gesicki 0.495
11. Zach Ertz 0.494
12. Kyle Pitts 0.493
13. Noah Fant 0.487
14. Tyler Higbee 0.477
15. Darren Waller 0.474
16. Jared Cook 0.464

Andrews finished as the No. 1 Fantasy tight end, averaging 17.7 PPR points per game. He also was among the best value picks in 2021 with an ADP in Round 5 as the No. 4 tight end off the board behind Kelce, Kittle and Waller.

Andrews' win percentage matched his Fantasy production, and Kelce and Kittle weren't far behind. Waller, however, disappointed many Fantasy managers, mostly because he missed five games with a knee injury that he sustained in Week 12.

Pitts was the No. 5 tight end selected based on ADP, and his Fantasy production was somewhat of a letdown, averaging just 10.4 PPR points per game. His win percentage was also low, but he should be exceptional in 2022. He'll be among the most popular breakout candidates, and he should be drafted as early as Round 3.

Knox was among the best surprises in 2021, and he averaged 10.9 PPR points per game. He was likely added to many successful Fantasy rosters as a free agent during the season, and you can see his win percentage was among the best at any position in 2021.
