I don't think replacing his production matters, so long as the team is as efficient as it was last season.
I know this has been discussed ad nauseum, but while his yards and receptions were good, he disappeared at times and was never a threat in the red zone and his TD production, compared to his total yards and recpts were way, way off kilter to each other... His stats were very misleading for a WR. Can his 3 tds be replaced from last year ?? Probably fairly easily... The point is, that was only part of the reason he was traded. I have no qualms about them trading him for the whole package he presented to our team...poor on field team mate, disgruntled messages to the press (although I don't know why, he was the one not getting into the endzone), off field issues, entanglements with the law...it all added up to a mess for the Fins brass. I wish him luck in Chitown. I wish him luck with his personality disorder. But the facts are that his production here was lacking...considering his job as a WR...
