5. Jamaal Charles Best Case: Andy Reid comes to Jesus, curbing his pass-obsessed tendencies to make Charles the true quarterback of his offense. It results in the greatest season of Charles’ career, who makes like Larry Johnson on the ground (1,700 yards) and Brian Westbrook through the air (600 receiving yards). Worst Case: Reid’s square peg (Alex Smith) doesn’t fit in the round hole (his pass-happy West Coast offense), hamstringing the offense, and Charles in particular. Charles still eclipses 1,500 yards from scrimmage and 5.0 yards per carry, but as is usually the case with Reid’s running backs, people are left wondering what might have been.
