re: Anybody else think Key should be benched?

I'm torn.

On one hand, we could use the experience on the field. And I did see on play against Troy where Key (apparently with no prompting from anyone), pre-snap, run all the way across the field and lined up somewhere between where a DE and the slot reciever would be, he was out in no-mans land all by his lonesome. I thought he had lost it. Troy ran an end around right to him. He sniffed it out; notable was that means Aranda had both figured it out AND communicated it.

On the other, if he's only effective X number of plays due to conditioning than that experience isn't being utilized. Some young buck should be in there.

So the answer lies in saving him for both pivotal downs (3rd and medium or long) and pivotal series.
