Matt could have run a 4.9 and put up 35 reps and it wouldn't have mattered, those measurements are not really looked at when evaluating OL's at unless they are really bad or freakishly good.
There are many things to complain about when it comes to Omer, how many bench presses our guys do at the combine is not one of them. In fact if you take alook at recenty history you would find that most of our players have done above average for their position in the bench press.
