A lot of strawmen in that argument. Not even sure how Rothliesburger being a pile of shit works into Brown not being a cancer in Green Bay.
I'd prefer the new coach to shake things up.
Fair point on the Big Ben-Brown dynamic.
The main point is that I think the reward greatly outweighs the risk, and the worst case scenario is that he does become a cancer and you cut him. I wouldn't sign him as a free agent for a 90 million in guaranteed money (a Khalil Mack type contract) because then you are stuck and can't cut him. But to get a Hall of Fame receiver near his prime for a third round pick and a 12 million dollar cap hit if it doesn't work out is worth it.
