You may have overlooked some players on draft day, but now they have become prime free agent pickups in Fantasy football after Week 1. Mark Ingram is suddenly on the Fantasy radar after operating as Houston's lead rusher in its season opener, as he carried 26 times for 85 yards and a TD. Should Ingram be considered a preferred pick among your Week 2 NFL Fantasy football waiver wire targets? New Orleans tight end Juwan Johnson burst onto the scene with two TD receptions in the first week.

Should Johnson be one of your top Week 2 Fantasy football waiver wire picks? And which other players on Fantasy football waivers are worth grabbing to plug some early-season roster holes? Before determining who to target on the Week 2 Fantasy football waiver wire, be sure to see what SportsLine's resident Hall of Famer, Scott Engel, has to say.

Engel is an inaugural member of the Fantasy Sports Writers Association's Hall of Fame. He is a four-time FSWA Award Winner and 10-time nominee. In 2020, Scott was a finalist for the FSWA Fantasy Football Writer of the Year Award, which he also won previously.

Top Fantasy football waiver wire picks for Week 2

One player Engel is advising Fantasy players to target on the Week 2 waiver wire: San Francisco running back Elijah Mitchell. Once again, Raheem Mostert is injured, and this time he'll miss the entire season after undergoing knee surgery. Mitchell has made a quick and strong case to be the 49ers' lead running back. He unexpectedly busted out in the season opener vs. Detroit.

When Mostert went down, Mitchell rushed for a surprising 104 yards on 19 carries, with the big highlight being a 38-yard TD run. Mitchell was drafted in the sixth round by the 49ers this year, and was projected to be low on the San Francisco RB depth chart. But Trey Sermon was a surprise inactive on Sunday, and Mitchell seized the opportunity in a big way.

Kyle Shanahan has often rotated his running backs, much to the chagrin of frustrated Fantasy players. For now, though, Mitchell seems to have earned the chance to be the No. 1 RB for the Niners. Sermon was outperformed by Mitchell and JaMycal Hasty in the preseason, so he will have to work his way back into the mix while Mitchell would appear to have the best shot at being the lead guy for now.

Engel is also strongly recommending Arizona WR Christian Kirk. Kyler Murray threw four TD passes in the opening week win vs. Tennessee, and Kirk caught two of them. He finished with five catches for 70 yards. Now in his fourth year, Kirk may finally be ready to deliver a true breakout season. 

A.J. Green was a highly publicized offseason addition for the Cardinals. But he caught only two passes for 25 yards on Sunday, and it appears he is well past his prime. As the Cardinals offense continues to roll, Kirk may become the second-best Fantasy WR on the team behind DeAndre Hopkins
