Lets be fair: Mack and Thomas were beasts, but the guards had injuries all throughout. Remember Pork Chop Warmack? Jason Pinkston? Schwartz didn't really become a positive on the line until his free agency year, classic Browns move. Guards were indeed a problem.
As for the QBs, McCoy thought he was a dual threat and always looked to run, often finding out college defenders are three steps slower than the pros. Weeden had the pocket presence of an old balogna sandwich you forgot about last Tuesday. Hoyer had more success than the other chumps, but problems staying healthy his first year and then a GM who hated his guts/ no center worth playing.
On we all move, this looks like a hedged bet that might work out in 2017, but definitely sets the franchise up for success in 2018.
