The Browns in 2014/2015 had Joe Thomas, Alex Mack, Joel Bitonio and Mitchell Schwartz. That's one of the best collections of talent I've seen on one line. Thomas is a HoF. Mack got a couple of ridiculous contracts. Bitonio was Thomas redux in just showing up every week and doing a good job keeping his QB upright, including two first team All-Pros. Schwartz won a SB with the Chiefs and was a first team All-Pro. Greco is... definitely a name I'd believe existed (sorry John, I'm definitely not as familiar with your work).
Nine first team and eleven second team All-Pros between them all.
The QBs they blocked for in 2014 and 2015:
Hoyer
Manziel
Shaw
Josh McCown
Davis
I think that's as comprehensive disproving of both theories as possible.
Neither.
