With coach Ken Whisenhunt becoming the next coach of the Tennessee Titans, Whisenhunt and G.M. Ruston Webster will have two critical questions to address. First, who’ll be the quarterback? Second, what will they do with running back Chris Johnson? Whisenhunt thrived in Arizona when veteran Kurt Warner served as the starter. After Warner retired, Whisenhunt and former G.M. Rod Graves gave up millions of ultimately unearned dollars (and a second-round pick) to get Kevin Kolb. Whisenhunt and Graves likewise swung and missed on various rookies and other assorted journeymen before both were fired.
