Fantasy Upside
The Colts are lacking a No. 2 WR with Donte Moncrief signing with Jacksonville. That gives Chester Rogers a chance to emerge as the slot receiver of an Andrew Luck offense. The Colts also did little to address the position, signing Ryan Grant to a one-year deal and picking Deon Cain in the sixth round of the draft. Plus, Rogers is free in drafts right now, mostly going undrafted.
Fantasy Downside
The downside is that this offense will spread the targets around, outside of T.Y. Hilton commanding a massive target share (as he has in the past with Luck at quarterback). Plus, Luck has enjoyed targeting tight ends when not looking Hilton's way. Rogers just may not see enough targets to be a reliable weekly option this season.
2018 Bottom Line
The good news is that Rogers is mostly going undrafted in fantasy so far in 2018. If you believe in his opportunity, it costs you next to nothing to get him. Just don't be surprised if you're cutting him before Week 3.
