Well, in both cases, they are very misleading.Again, with removing the results that you don't like. We've been down this road before. A RB's stats are what they are. A QB's stats are what they are.
Plummer's 70+% completion rate is misleading in that he never throws the ball down the field...aside of one big run on a play where ND messed up, Doerue/Purdue did not have any success running the football, and, most importantly, it was completely incapable of running it when it needed to.
It is not a result that I don't like...it is a fact...Purdue did not run the football with any sustained success...it had a successful play that completely skewed the stats.
