I kind of like the idea of drafting an OT in the first round and let him develop for a year, if it's the right guy. We may have 5 starters but you're right, 3 are free agents, injuries happen, and it's not like Bulaga and Bakhtiari were that good last year.
I still prefer a DL though, as it sounds like we could get a potential top 10-15 guy in most years at #27. Value seems to be there and it's a huge need with Daniels and Guion the only NFL caliber starters in the group.
