Imagine if Luck doesn't get it together. When Brady retires/declines there will be one great QB in the league. When Rodgers does the same no one will be any good. Who's the next best QBOTF besides Luck?
Maybe the Chiefs will have a chance then if everyone's QB sucks.
Of top 8 QBs on this list, only Luck isn't at the peak or downside of his career:

That leaves the future looking like Wilson, Luck, Cam, Ryan, Tannehill. Not even remotely in the same class as Brady/Brees/Manning/Rodgers in their prime.
