For example, Brees is 40, if NO ends up with a top 10 pick, they're gonna be looking for his replacement. Big Ben is getting up there in age as well, steelers look like they could be a top 5 pick, they're going to be looking for Ben's replacement, or at should.
Its not that the injuries are career ending, its that some of these teams have QBs nearing the end of their careers regardless. Others, are dealing with injury prone QBs.
I'm just saying that the competition for the handful of decent QB prospects is gonna cause any asking prices for a trade to balloon in the next year or two.
