“Mike Glennon is so far more advanced than RG3 playing NFL quarterback that it's not even close,” Cosell said during an appearance on 98.7 The Fan in Tampa Bay. ”They shouldn't even be in the same discussion.”
“I think they (the Bucs) are getting really quality quarterback play from Mike Glennon, who is without question the best rookie quarterback in this class,” Cosell continued. ... “When your quarterback makes difficult anticipation throws, everything about your offense tends to look better.”
And when your quarterback heaves an off-balance arm-punt into the end zone that's intercepted, the offense tends to look noticeably worse.
