Bouchette is arguing to take the pick rather than keep Sanders, but there's a lot more to the argument than just his evaluation of Sanders' ability as a player, including the ability of Pittsburgh to sign Sanders to a longer term deal if they match. He factors into his assessment that the Steelers are in "transition" and could use both the pick and the cap headroom...pretty much arguments that have been thrown around a lot on this board. Methinks Sanders is reading a bit too much into Bouchette's comments, and is being pretty selective in what he's responding to. You have to see the whole blog entry (I'd link but it's a subscription).
The worst that Bouchette writes about Sanders is that he's a "nice" WR but "no Lynn Swann"...which could be said about 99% of the WRs in the league. He says he would be a "lame duck" starter, but that's again due to the expectation that Sanders would walk for more money elsewhere. (Wallace's overall suspect focus level last year in his "lame duck" season is something I'm sure has crossed the minds of Pitt's decision makers re/ Sanders).
He also makes what I think is a compelling argument for taking the pick: namely, if a WR of Sanders' caliber and pedigree were available for Pittsburgh's 3rd rounder, would we make that trade (or signing)? The answer, most likely, is no.
Anyway I don't see that Sanders is being wronged in any way by Pittsburgh's media or its fans. I think Sanders is guilty of "rabbit ears" here, and is taking large offense where little has been given. I'm sure most Steelers' fans would love to keep him, but under the circumstances it might be better to get the compensation while we can.
(BTW Sanders *did* sign an offer sheet with another team. Absolutely nothing wrong with that...but then again there's nothing wrong with Pittsburgh fans or media reacting to that signing objectively...which for some means concluding that it's best to take the draft pick.)
One thing no one is really talking about is the opportunity for Sanders himself. Obviously he's going to an excellent organization and QB situation if he goes to NE. But the Pats have had FAs come and go at WR, and there's no guarantee that Sanders will better than a 4th option. He's learning a new offense as well. In Pitt he'd be guaranteed a starting spot, in a system he knows, and would at worst be the #3 option (frankly, more likely the #2 option with Miller hurt). Roethlisberger might not be Brady but he's not a bad QB option himself. Sanders seems like a good kid, so I hope whatever he chooses works out for him...but if he were just trying to rack up numbers on a one-year deal with an eye towards UFA, the situation in Pitt seems like more of a sure thing.
