I don't mind Glenn. I think that at #13, it's reaching a bit. The Ravens player personell directer Eric DeCosta, who's pretty adept at drafting value, has him rated "in the 15-35 range", as of April 2. Now he's moving up charts partly because of his line versatility, but there are questions on him being able to handle outside rushers, just like Levi does. They still have him mainly as a LG, where he is in his most natural element.
He also does not have great initial burst but is strong.
