I watched that last night and it did seem he did look bulked up. I was glad. Most players that come out of College and get Drafted into the Pros get into a Pro lifting Program when they come back for their 2nd yr you can usually see they added some mass.
The Offensive Lineman the transformation is kool to see. Plus everything else from trainers to nutrition it really helps as some schools they come from are limited.
GO RAMS !
