You are entitled to your opinion, and the nice thing about this board versus the other one you mentioned is that here people generally respect different opinions. I was high on Clemmings before the draft, but read that he really did have a shocker at the Senior Bowl, and that coaches were concerned that he wasn't learning there. The foot injury didn't help, either, but given how far he fell, we obviously we're not the only team with concerns about him.
I knew very little about any of the OL we drafted before we took them, but have been impressed by what I have seen and read since. I know Havenstein wasn't required to pass protect much, but his low number of penalties is impressive. Compared to Barksdale, my view is that he has more upside as JB has had plenty of opportunities to improve his pass protection and has shown that he can't do it very well, while Havenstein could still improve that. I like the speed of Brown and Wichmann, and think Donnal could be a good all round OLer with a bit more strength conditioning. His feet looked pretty good to me. Given the o lines that coach Boo has built before from inferior pieces to these, I am really optimistic that this young, huge o line could be really good.
