Because certain biased individuals fail to see the positive impact of having a quality QB on your team, and also cannot see the negative impact of having a terrible one, we will be looking at pff grades from both the Vikings (13 wins omg) and the Broncos (recently went from #3 pick to a playoff win).
QBs can tire defenses out if they have too many 3 and outs, pick 6s, 2 and INTs, or even my favorite, the 1 and fumble. They impact the OL because if you have no pocket awareness, and cannot move with the pocket, then pass blocking for them becomes impossible. They impact WRs, in the obvious way, by throwing catchable passes. Preferably further than 3 yards down field, and preferably at someone in the same colored jersey. They impact running backs because when they suck the defense can stack the box.
While keeping that in mind, let’s look at the grades. I will try to keep it to the players who Keenum played with and who he will play with this year. Also let it be known that I have resorted to using PFF grades because with the exception of maybe Balls and myself (I watched every Vikings game BTW) I honestly doubt anyone here has watched more than 2 Vikings games in the last year.
