As much as I love Peyton and everything he stands for, I think it has the potential to set us back years to take him. Paying big for past performances is almost always a recipe for failure. Look at Favre in NY, McNabb in Minnesota, and these guys weren't coming off severe nerve damage.
No amount of hard work, toughness, or attitude can make his nerve damage heal any faster or more than it's going to. He'll be 36, and then be gone in a year or two, leaving us starting over and again, no consistency. Building an offense around Peyton is not much different than building one around Tebow - he is the only one with the skill set to make that particular offense work, and when he's gone (injured or retired), you're starting over.
Hopefully, Philbin thinks Flynn is the real deal, and we can have our own young franchise qb again, rather than trying to rent someone's past glory.
