Thomas McBride hit the weight room hard between his junior and senior seasons.
The FPD center put on 50 pounds, giving the Vikings a strong anchor on their line of scrimmage.
McBride, who now has 280 pounds on his 6-foot-2 frame, went to a couple of Mercer camps while he was putting on the weight. He signed with the Bears on Wednesday.
As of 10:45 a.m., McBride was one of five offensive linemen to have signed with the Bears.
