I agree with you. If Barron's shoulder checked out at the combine, I can't see Titans, Lions, & Chargers all passing on Barron. Don't count out the Browns if they trade down from #3. That was a freakish workout Alex put on today and let's face it, NFL scouts love freaks.
There are other good tackles that can be found in this draft. The Texans may or may not take a tackle in the 1st round, just as they may or may not go after a big free agent. Who knows what's really happening when Charley starts blowing smoke? But currently, the Texans have Chad Beasley & Garrick Jones listed as the backup tackles. They will draft an offensive tackle at some point in the draft.
