So far, the #1 OL unit has been the same for all the practice sessions the media has observed - LT Jagusah, LG Coogan, C Craig, RG Schrauth, RT Baker - but that doesn't mean there isn't an ongoing competition. Craig seems to be a lock at C. Jagusah is likely a lock at LT but the RT is still open between Baker and Wagner and Spindler still has a shot to get his job back at RG once he's 100% healthy (even if most people think Schrauth is the favorite).
It's important to note that last spring and early fall the 1st OL unit seemed to be set but then Coogan and Spindler won starting G spots when Schrauth and Baker (if I remember correctly) were too inconsistent. The point is, it's nice to know who's running with 1s at OL during the spring but that doesn't mean the competition is over and there won't be changes heading into fall camp.
