Weatherford Decision Puzzling

It is puzzling to me that Bobby Bowden will start Drew Weatherford over Xavier Lee. Weatherford has had his chances for 20 games now and has not gotten it done. I question the reasoning by Bowden that Weatherford graded out better. Here are their numbers for the Wake game:

Drew Weatherford Attempts/Completions-15-4-2 (26.7%)
Passing Yarda-52
Sacks-4

Xavier Lee Attempts/Completions-13-5-2 ((38.5%)
Passing Yards-61
Sacks-1

They both had two Ints but Lee had more yards(61) and less sacks(1). Lee's completion percentage was higher than Weatherford also. Wait, maybe it is because Drew is more mobile.Nahhhh.Very strange.
