Geoff, excellent thought provoking question. While Roy and Shipley are clearly the guys who have done the most, had many seasons of excellence, there are a bunch in the next group who had outstanding seasons (1 or 2) in the next tier.
I don't think he'll have the impact of many of them. Hope I'm wrong, but right now I'd buy the careers of Quan Cosby or Mike Adams over Worthy. Duvernay and Humphrey were outstanding. I can't quite understand why it took so long for Texas to figure out what they had in Duvernay, but he was outstanding.
