Way to early to know Leftwich's future success or failure but having watched his interviews both prior to the firing of McCoy, his post promotion interviews and the interviews after the 49ers game its really hard not to like this guy.
He seems to carry an air of just the right mix of optimism, humility, even temperment and slips in a little self deprecating humor during interviews. Hopefully that charisma can carry him through the rest of the season while he gains the OC experience necessary to make him a successful coach.
