There's a couple of reasons that I'm not going to wax poetic about Dez Bryant's fit in the Saints' offense. For starters, it seems like a bad omen to do so after the last time a sense of unbridled optimism accompanied his addition it took all of a couple practice routes run before the sobering subtraction of his functioning achilles.
In line with that, while time might heal all, Father Time has a way of making the recovery period from a devastating injury that much more extensive. Especially for a 30 year old player who was highly reliant on his athleticism before spending a full year out of professional football doing nothing more than watching and recuperating. The truth is that no one knows anything close to the truth about what Dez Bryant can still bring to the gridiron, so it's tough to opine on the entirely unknown.
That being said, as a low risk/higher reward signing, I can't see why the Saints wouldn't be interested in giving another shot to someone who has plenty to prove by adding him to a locker room that seemed to embrace him immediately. Banking on him as their premier pick-up at a prioritized position would be about as safe and sound as saving money under a mattress, but Dez Bryant makes plenty of sense as another fish in a pool of potential playmakers being given an opportunity to make a splash behind Michael Thomas.
While I think he got a bit of a raw deal towards the end of his tenure in Dallas, I can't imagine he sees himself as worthy of much more than the low price of a one year, prove it contract. If that's all it takes then I'd be glad to see him get the chance to finally start throwing up some X's in NOLA, as opposed to having them thrown up in his honor.
