The first day of NBA free agency didn't provide much for Fantasy players to get excited about, and the next few days didn't do much to change the outlook for next season either. Everything hinged on what Kevin Durant decided to do, and the market couldn't truly move until he did.

Well, move he did, Wednesday -- literally -- opting to leave the Oklahoma City Thunder for the Golden State Warriors in a move that shakes the very foundation of the NBA in a way nobody but LeBron James could manage this summer.

With Durant joining the Warriors, Golden State now has the two players who have combined for each of the last three NBA MVP awards, and they also have the two top contenders for the No. 1 pick in Fantasy. The combination of Durant and Curry -- with Klay Thompson and Draymond Green, to boot -- makes the Warriors the team to beat in the NBA for about the next five years. It also fundamentally chances the Fantasy landscape for years to come, beginning right there at the top.

Taking a step back

Curry has been the obvious choice at the top of Fantasy drafts over the last two years, and the results have been tremendous. With his injury concerns well behind him, Curry has played 80 and 79 games in the last two years, and put up huge numbers across the board.

Last season in particular, Curry might have somehow surpassed Fantasy owners' expectations, despite being the unanimous choice for the No. 1 pick. He led the league in points and steals per game (30.1 and 2.1 per game, respectively), while adding 5.4 rebounds and 6.7 assists per game, and shooting 50.4 percent from the field. Curry was a model of efficiency -- even leading the league in free throw percentage for the third time -- but he was also the best volume scorer, breaking his own record for 3-pointers made in a season by an incredible 116 makes.

Curry was the No. 1 player, but Durant would have had a serious case for the top spot nearly any other year. Durant played in 72 games after missing 55 in the previous season, and averaged 28.2 points, 8.2 rebounds, 5.0 assists, 1.0 steals and 1.2 blocks per game. Durant didn't dominate any one category like Curry did, but he provided a level of all-around brilliance rarely matched in the NBA. In fact, he become just the seventh player ever to average at least 28-8-5 in a season, and he was the only player to do so while making more than 100 3-pointers in a season.

If you were going to draft for Fantasy 24 hours ago, Durant and Curry would have almost certainly gone No. 1 and No. 2 in nearly every draft. However, after Durant signed in Golden State, it might be hard to justify either player at the top spot.

Oh, they'll still be terrific, and this team is going to be an absolute handful to deal with, with Durant, Curry and Thompson constituting the single best concentration of shooting talent in NBA history. However, there are suddenly a ton of mouths to feed in Golden State, and a coach who is willing to limit minutes for his stars when he gets the opportunity. That isn't great news for Fantasy, in a game where volume still matters a ton.

The end result should be incredible efficiency for the Warriors offense, with a real chance for the best offense ever seen in the NBA. However, the Warriors might be a bit too stacked for Fantasy, with both Curry and Durant possibly set to see a decline in both minutes and shots as a result of their team-up.

That could open the door for a new No. 1 overall player in Fantasy, and Durant's former teammate seems poised to step up.

A new No. 1?

Russell Westbrook finished third in Rotisserie scoring last season, behind Curry and James Harden, and this season represented something of a step back for the explosive guard. Westbrook improved his overall efficiency and playmaking, but saw his scoring dip, from a league-best 28.1 points per game in 2014-15, t0 23.5 in 2015-16. He could get back to that previous level without Durant around.

Westbrook has played 48 games without Durant since the start of last season, and the results have been simply stunning. While his efficiency has taken something of a hit (41.3 percent from the field), Westbrook has put absolutely insane numbers without Durant over the last two seasons: 31.5 points, 8.3 rebounds, 9.5 assists, 2.2 steals per game.

Okay, he also turned the ball over 5.4 times per game, another insane rate (this time not in the good way), and the efficiency left something to be desired. However, if you're average close to a triple-double on a nightly basis, a few turnovers or missed jumpers can be excused. If Westbrook's performance in the absence of an oft-injured Durant in recent seasons is any sign of what is to come, Fantasy owners might have to consider Westbrook at the No. 1 spot. The drawbacks are obvious, but the upside might be too much to pass up.

Oklahoma City shakeup

The Durant signing will have other very interesting ripple effects too, as the Thunder have now pretty much dismantled the core of that team that made a run at the NBA Finals in 2011-12. With James Harden long gone and Serge Ibaka recently dealt, they are left with an almost entirely new cast surrounding Westbrook. Who steps up is to fill Durant's Size 18's will be one of the most interest questions in Fantasy this offseason, even without projecting massive numbers for Westbrook.

The most obvious beneficiary is Victor Oladipo, acquired in the trade that sent Ibaka to Orlando. Oladipo has had an up-and-down career, with flashes of brilliance alongside months-long stretches where he seemingly can't hit a jumper. His problem is that he isn't quite capable of playing the point, but hasn't had enough help to really make taking a back seat a viable option in Orlando. It's safe to say he'll have help in Oklahoma City.

Oladipo likely emerges as the big winner from Durant's move to Golden State, as he will likely enter the season as the No. 2 option for the Thunder. With Westbrook there to take pressure off and make plays for him, Oladipo could be looking at career-highs in shooting across the board, with a return to near-20 PPG scoring averages and his typical solid production elsewhere.

Steven Adams should also stand to gain from an increased role. Adams' development ultimately made Ibaka replaceable, and the 24-year-old averaged 10.1 points and 9.5 rebounds per game in the playoffs, numbers he could improve on with Ibaka and Durant out of the way. However, he was so impressive in the playoffs, Adams might be too popular a breakout candidate to get at anything approaching a discount for a player who may not have No. 1 center upside.

Another player absolutely worth keeping an eye on is Enes Kanter, whose big contract all of a sudden doesn't look so bad in the new cap landscape. Kanter averaged 18.7 points and 11.0 rebounds per game after a trade to the Thunder in 2014-15, with Durant sidelined by injury. He and Oladipo might be asked to step up to fill the scoring void left by Durant, and Kanter might even find himself in the starting lineup following Ibaka's departure, after coming off the bench in 81 games a year ago.

This is going to go down as one of the most interesting moves in NBA history for about a thousand different reasons, and the Fantasy ramifications could very well change everything about how you approach your season come October. For now, nearly four months out, I'm seeing a slight decrease in Durant and Curry's value -- and potentially Thompson and Green, too! -- with a boost for the Thunder players KD left behind.

Durant obviously leaves a massive void to fill, but, luckily for Fantasy players, the Thunder might just have a roster capable of filling that hole. There is an opportunity for younger players to step up, and if they make the most of their opportunities, there is a ton of opportunity for value in Oklahoma City.
