SANTA CLARA, Calif. – It's no secret that Jim Harbaugh wishes he was still an NFL player.The San Francisco 49ers coach, who was an NFL quarterback for 14 years, calls his players "teammates", he often warms ups before games and he even wears cleats on the sidelines.It's in his blood. And he so badly would like to get on the field Sunday when his team plays the Seattle Seahawks in the NFC championship game. How badly?"I was thinking of the things I would trade to be able to compete as a player in these games, in this game," Harbaugh said Wednesday.
