He molded Ben Roethlisberger in Pittsburgh. He revived the career of Kurt Warner in Arizona. The proof is in the pudding: when Whisenhunt has a quality quarterback spearheading his attack, he is successful.
Whisenhunt will get the most of Philip Rivers. Whether that is enough to shape the Chargers into a contender remains to be seen.
QB Philip Rivers

However, he's turned the ball over 47 times the last two seasons. And his fourth-quarter magic melted away as he missed opportunity after opportunity to author game-winning or game-tying drives.
Enter Whisenhunt, an expert on protecting QBs and putting them in position to excel. He worked with Roethlisberger, infamous for holding the ball too long, and Warner, who was even less mobile than Rivers. He helped them both perform at optimum levels.
It is amazing the Chargers had a chance to land Whisenhunt as an assistant. If not for Baltimore's upset for the Broncos, McCoy would still be coaching and Whisenhunt would likely be San Diego's head coach.
Now the Bolts get two of the game's elite offensive minds -- McCoy and Whisenhunt -- to help reshape an offense that ranked last in the AFC in 2012.
Whisenhunt brings with him Frank Reich, his former receivers coach in Arizona who will coach quarterbacks in San Diego. The Chargers literally could not have done more to get Rivers prepared to have the best season of his up-and-down career.
Some Chargers fans feel Rivers isn't a franchise QB and should join Norv Turner and A.J. Smith in the club of wayward Chargers. With Whisenhunt calling the plays, Rivers will once and for all either silence those critics or give them complete validation.
