The thing is that every one agrees that this is not a strong QB class... yet ... many have four QBs going 1st round?
My feelings are that a few of the teams needing QB, including the Bears, are going to take a fly on drafting them in the 1st round and several of these top rated QBs in this weak class of QB won't go off the board until the 2nd or later round. And I base this off recent drafts when there were several teams needing QB yet took BPA at another position rather than over draft the weak QBs.
QBs taking first round last ten years
2007 - 2 - Russell(1), Quinn(22)
2008 - 2 - Ryan(3), Flacco(18)
2009 - 3 - Stafford (1), Sanchez(5), Freeman(17)
2010 - 2 - Bradford(1), Tebow(25)
2011 - 4 - Newton(1), Locker(8), Gabbert(10), Ponder(12)
2012 - 4 - Luck(1), Griffin II(2), Tannehill(8), Weedon(22)
2013 - 1 - Manuel(16)
2014 - 3 - Bortles(3), Manziel(22), Bridgewater(32)
2015 - 2 - Winston(1), Mariotta(2)
2016 - 3 - Gofff(1), Wentz(2), Lynch(26)
I just can't see four coming off the board first round this year.... even in years with strong QBs four were a lot..... I see at best two maybe three.
