Slow down there. First of all Martin isn't playing like that now. So don't think any player stepping into that position is replacing this current All World future HOF'er that walks on water. Second, yes he can step in and replace Martin and eventually become an above average starting OG in this league. That's the best anyone can hope for unless he can elevate his game to Tyler's status. It's very very rare to replace a future HOFer with a future HOFer. Just because he is a UDFA doesn't mean he can't do it. It's happened before (it happened right here with the Cowboys) and will happen again.
There are some in here that think we have guys who can step into Lambs and Parsons shoes and can replace them so those players should be traded!
