You can't fill every hole with superstars. There have been lots of UDFA OL who have succeeded. Using one of our top two picks on an OL increases the competition for those spots and allows us to address other needs with Day 1 and Day 2 picks.
I'm not a fan of just handing the center job to Hoffman, who we cut in camp and no one picked up, which is why center is higher on my list, but I feel pretty good about Richards and Bass competing with Tyler for two starting spots. If Hoffman does step it up, then we can add the center/guard candidate we drafted in the first join that competition.
