I think the ONLY draw back would be the media attention. Green Bay is notorious for being a humble, camera-shy (except for you Finley) organization without many hiccups as far as spot-light players for the wrong reasons. Walden and Jolly (and I think Underwood, if I remember right?) are a few minor examples, but it doesn't happen often.
Tebow would at least be positive recognition. For as much as I dislike him as a QB, I do think he is a positive role model and someone that brings youth to the field. Now if he DID land in Green Bay, as unlikely as it seems, would you have a problem with him backing up Arod? I wouldn't, and here is why:
I would NOT like him as a backup for the purpose of being a security blanket to Rodgers. I would like Tebow as a situational QB, where his role has really shined when he first took his snaps. Tebow is a naturally athletic monster and there is no arguing that, he is probably more elusive at his size than anyone else at his position, and although he doesn't have great speed he seems to have amazing awareness when on his feet.
This kind of talent would be put well to use in goal line situations, which the Packers are severely lacking skill with in terms of running the ball. A lot of my friends seem to think that this would be predictable, but even if it is predictable you STILL have to stop Tebow from scoring, which I have yet to see many teams do when that close to the goal line.
So my idea is, Rodgers (assuming he doesn't score from 50 yards away like he is so good at) brings them within 5 yards, then we give the ball to Tebow and let him work his magic. 8/10 times we probably just play power football and have him run it in, but maybe every now and then we get tricky and have him pass to keep the defense honest.
Your thoughts?
