The WITH McKinney was not very great last year. And that was with a Pro Bowl LG who is no longer on the roster. The dude's effort when he IS on the field is clearly lacking. Everyone can see he is whiffing on blocks. So why is it so hard to believe that his effort on the practice field is also lacking?
McKinnie was an above average pass blocker last year, so Im not sure what youre talking about. Sounds like your making stuff up in order to support your theory.
Hes never been considered very good in run support, so thats a non issue.
