I can't believe all the "we want Kindle" folks on here!
Being an Aggie Mom I saw his play in the Longhorn-Aggie game last year and yes he was great.
But still, he's got medical issues...one of which is narcolepsy.
My aunt has narcolepsy. Even though she was on narcolepsy control meds, she still managed to crash her car into her garage door coming home at night because when she pulled up to the driveway, she had a narcolepsy episode!
These episodes can be instantaneous...do you really want Kindle on the Fins being out there on the field playing outside linebacker against, say, the Bills CJ Spiller, and he misses a tackle because suddenly he has a narcolepsy episode and he falls down asleep?
