Too many have excess of wealth syndrome with the OL. 3 1st round picks and Collins would have been so make that 4. First OG to make All Pro in his rookie year since 1947.
The Cowboys need to address the LT spot before any other on the OL and if Big Smitty goes another season, that's fine, got some depth.
The team is going to have to have some just good players because of how they pay the stars and while Williams hasn't come on like they planned, he has improved and if you watch those times he gets bull rushed, it is his technique and leverage point. But let's be honest, some of those behemoth DT's are going to bull rush any interior OL. We do not see how many times they get beaten unless that player gets a sack or tfl.
If you look back on McC's time in GB, you will see a mixed bag of OL and one thing he understands as well as any HC, they need more than 5 of them.
