I think it's worth mentioning that in the "Drain the Swamp" victory in 2001, Travis Stephens played the game of his life (226 yards). As a matter of fact, Travis' rushing yards outnumber Casey's passing yards. This is with an incredibly stacked receiving core of Stallworth, Washington, and Witten.
Casey was cool under pressure and he was generally good at taking care of the ball. However, from a talent standpoint he wasn't very accurate and his arm strength was average at best. I'd take Ainge and Martin over him. If we're talking about raw talent, I can only imagine what Bray would've been like with that 2001 receiving lineup, amazing defense, and Stephens to hand it off to.
In his 14-1 road record, only four of those teams were ranked and three of those ranked wins were against sec teams. Yes, he beat Florida twice but he wasn't much of a factor in the first win. I remember his OT victories over unranked Arkansas, Alabama, and South Carolina teams. I also remember wondering why we were struggling so much to put away those teams in regulation. Casey had his clutch moments but this "iceman" thing has gotten ridiculous.
