I heard all these knocks on Bulaga over the course of the last few weeks: he has short arms, he projects to be a RT, he got owned by Derrick Morgan in their Bowl game last year.
Then I watched Bulaga's highlight reel. Needless to say I was impressed and would not mind at all if he was the Bills pick and you make some great points to further elucidate that point. I've read that scouts think that he is the 2nd best LT in the draft and I could easily see him gone before the Bills pick.
However, I know you have quite a few aversions to Clausen, Senator, and I had mine too, but I still think if the Bills brass had to choose between Bulaga and a franchise LT, I think they choose Clausen.
