The Patriots system was largely carried by Tom Brady though lol same as the Packers .They are converting from the Patriots system (6 SB and 9 SB appearances wins in 20 years, after a successful run under Parcells (with a SB appearance) and a decline when going away from that system to Carroll's), to the Packers system and the Browns system. The Packer's system has had 2 of the 20 best QBs in NFL history carry it for30 years. It produced 2 SB wins and 3 appearances. The Browns haven't won a fucking thing.
But at least they new way will be diverse and inclusive!
We shall see. I'll be patient and give it at the minimum 3 years with improvement each year and be contenders by year 3
