Truth be told, in Fox's world that’s a perfect blueprint for success.
Still, some can’t understand why Fox remains so loyal to Delhomme, whose interceptions drive fans crazy. To comprehend that, it’s first necessary to understand what Fox looks for in a quarterback. Earlier this week, I asked him just that question.
His reply?
"The way I look at it, I think one of the most important qualities is a guy that's got some command, got some leadership," Fox said. "The second thing would be smarts. And third might be how he throws and all those measurable things. That's how I look at the quarterback position. Everybody's different. I feel like Jake's all those, and he's won a lot of games."
