Fantasy football projections, Week 10: Rams vs. Colts featuring Zac Stacy, Andrew Luck and T.Y. Hilton

The Week 10 matchup between the St. Louis Rams and Indianapolis Colts features two intriguing running back stories. We've got all the fantasy projections for you courtesy of numberFire.

Running back Zac Stacy appears to be the real deal in the real world and in fantasy land. He's the main reason the Rams are able to keep games even slightly close on the offensive side of the football, especially with Kellen Clemens quarterbacking the team. After both Daryl Richardson and Isaiah Pead failed to do anything productive for weeks, it is Stacy and not the former Rams starters that is bringing home the bacon. Stacy had 178 yards on 33 touches against the Titans in Week 9.

That said, he will need help from Clemens if the Rams are to upset the Colts in Week 10. Clemens is by no means a fantasy-worthy quarterback, but he has been a decent game manager in the absence of Sam Bradford, who's out for the season after tearing his ACL in Week 7. He'll look to tight end Jared Cook and receiver Chris Givens to carry the load through the air. Both pass catchers are averaging well below 50 yards per game this year and Givens has yet to find the end zone. Do the math: Stacy is the only Rams offensive player worth starting in your fantasy league.

Andrew Luck was able to quarterback the Colts to a victory over the Houston Texans despite the fact he waited until the second half to do most of his damage. Luck managed to go toe to toe with Texans rookie Case Keenum in the game despite the fact that Keenum helped wide receiver Andre Johnson to one of the best performances of his career. Fortunately for the Colts, Luck was equally good at finding his top receiver, T.Y. Hilton, against the Texans.

Hilton caught all three of Luck's touchdown passes in the game. He was clearly the team's best receiver despite the fact that his teammate Darrius Heyward-Bey was the player expected to emerge with Reggie Wayne out for the season. Hilton will face a pretty good Rams secondary but should still be a top play in fantasy leagues given his ever-growing rapport with Luck.
