Vince Young has made believers out of everybody. The final nail in the coffin came last Monday against the New Orleans Saints, when he piloted the Titans to a 31-14 victory. He’s a leader, and he can throw the ball some, too. No Michael Vick clone he.

Having said that, Young’s advanced metrics aren’t too hot – not even on the ground. Tony Romo of the Cowboys, on the other hand, is ranked third among all QBs in passing efficiency, and second in running. His performance thus far is leaps and bounds better than his first full year in 2006 – which was already a Pro Bowl season.

We’re still waiting for similar breakthroughs from Matt Leinart, Jay Cutler and especially Alex Smith. But you don’t have to be a youngster to show some upside. Check out how Jeff Garcia has resurrected his career in Tampa Bay: two wins in three games and a 105.6 QB rating.
