I have always enjoyed Corso's shtick, but he needs to retire. He has not been the same since the stroke and they have him doing less and less. Outside a little at the beginning and the picks at the end, he really doesn't get involved in the talking about X and O's like he used to. I really wish they would hire Les Miles to take Corso's spot and let him pass the mantle of craziness on to the mad-hatter.
As far as this being Corso's livelihood, that is not necessarily the case. While in the last decade or so big money contracts are the norm for all these ESPN celebs......Corso was/is director of business development at Ticonderoga Pencils. That is why he always has a pencil with him on set. (Not so fast, my friend)
