They aren’t asking him to prove it. Really not any of the 3. Elliot won’t sign a 1 year prove it deal. None of them will.
Cooper and Prescott are in the last year of their contracts so they are on a prove it deal. And I have no problem with that.
Some are using the argument of giving a 1st for Cooper as a reason to make him a top 3-5 paid WR when he's only been there for half a season and has a spotty history. So what? Has this team not blown 1st round picks before? Hell, got one at DE right now.
They have Elliott on the option and can use the tag on one of the other two and draft the other position in this next draft. Either that or it's balls out and hope they can bring it home before the exodus takes place.
At some point they have to face the facts, they have too many up on the O side and are in jeopardy of getting unbalanced and not have enough to keep some critical pieces of the defense.
