Edelman out for the season with a torn ACL in the first 2min of a pre season game. This one is going to hurt.
It'll hurt for Edelman and certainly fans or a team always hate when one of the best players, and one of--if not THE--the emotional spark plugs of a roster gets hurt. But it won't hurt the Patriots, at least not to that large an extent.
Edelman was and is a fantastic slot receiver, they don't have a replacement for him. What they have, however, is Brandin Cooks who's a do-everything #1 guy; Chris Hogan, a stretch the field type with great hands; Amendola, super-reliable Edelman-lite slot guy; Malcolm Mitchell, who'd be starting for every other NFL team and showed great potential last year and had a baller Super Bowl; and add in Austin Carr who's a slot guy that's looked great in the preseason and has supposedly had a very impressive camp. Then consider Gronk and Allen, and White, Burkhead and Lewis who are all pass-catching RB's. Gillislee looks like he'll add an element to the offense.
For Edelman I couldn't feel worse; 31-year-old shifty WR's tears his ACL, we may have seen the last of his elite days unfortunately and the guy lives and breathes football, it sucks for him. For the Pats their depth got thinned a tiny bit but it's still an insane amount of talent at one position--and I never even mentioned that Brady fella, who's looked alright in his time in the NFL :)
