For a team as perma-bad as the Brownies, they’ve consistently had some surprisingly good units.
Joe Thomas played there for over a decade (made the Hall of Fame!), and they usually had excellent O-lines when he was there – especially when Alex Mack was also there, say 2010 to 2015.
Overlapping for most of the Thomas era, Josh Cribbs was an All-Pro return man for the Brownies in the late 00’s thru 2012. I was at the game in 2007 when the Brownies beat the Ravens on 300+ return yards by Cribbs (245 yds KR, 61 yds PR): he was unstoppable.
