The former Oregon Duck turns 25 on Aug. 12, the day after the exhibition opener against the Broncos at Soldier Field, so it would definitely behoove him to get his career into the fast lane this season. There was talk in the building after the draft that Cody Whitehair, this year's second-round pick, might be best as a center. But the way the Bears have the line set up right now, they could be young and improving for seasons to come with Grasu at center and Whitehair at left guard. Consider left tackle Charles Leno is 24 (turns 25 in October), right guard Kyle Long is 27 (turns 28 in December) and right tackle Bobby Massie turned 27 on Monday. That's a young bunch. There's no telling yet if that will be the five the Bears roll out in the opener, but it could happen.
