If Keenum gets the start, one of the big things to watch for is accuracy. It hasn't been there.
Gary Kubiak talked about needing to get Keenum to between 60 and 65% in completions. Keenum is at 54%. His high water mark was the debut against Kansas City in which he completed 60% of his throws. That's one out of his seven starts in the range where he needs to be to make this offense click consistently.
Matt Schaub has been sub 50% only four times as a starter. He entered the year number seven on the all time accuracy list. This season he's had problems finding the strike zone and failed to complete half of his passes the last time out. Had he beaten Denver, he might have gotten the automatic nod against Tennessee. But the loss, which included two picks, opened the door for Keenum to get back into the line up.
Even though the organization has gotten a good, long look at Keenum, it's still worth another shot if he's healthy. He has an extremely cap friendly contract and could figure into the depth chart at quarterback under the new coaching regime. Plus, he's taken some learning-curve lumps and just might bounce back big next season. If his off season is as productive as last year's then he'll certainly make noticeable strides by training camp.
