I watched the tape this morning and focused more on James and Hadnot after looking at Carey last night. No question Carey shows more promise than either James or Hadnot, even though I still think Carey is misplaced at LT. Hadnot has basic liabilities in quickness and lateral agility. James, as another poster mentioned, doesn't seem particularly strong and gets overwhelmed at times. At Carolina I remember he excelled in space, on the run in front of Stephen Davis or the guy from UCLA. Our schemes and the OL talent, or lack thereof, around him don't allow those type of slow developing plays.
McDougal isn't as athletic as you would expect from someone drafted in the first round, but he looks competent at RT and may improve. An obvious difference from Houck's teachings to those of the previous regime is a much shallower pass drop from the tackles. I thought it was just Carey, but after looking at the tape this morning all the tackles are doing it including backups like Alabi.
The interior of our line is a mess. Middleton is in the same type of shape at McIntosh last year. I'm not sure McKinney, Hadnot or James will be starting next year, at least not in Saban's ideal world.
