Garrett Wolfe does not believe in procrastinating. The record-setting running back from Northern Illinois became the first player in the 2007 draft to sign a contract, inking a four-year deal with the Bears on Tuesday. Financial terms were not disclosed. A third-round pick, Wolfe finished 11th all-time in NCAA Division I-A history with a school-record 5,164 rushing yards. His average of 156.5 yards per game is surpassed only by Ed Marinaro, O.J. Simpson and Herschel Walker. But the 5-8, 183-pound Wolfe did not get selected until the Bears took him 93rd overall because many scouts were concerned with his slight frame.
