The Mario changed the narrative that no free agents will ever come to Buffalo and that Buffalo isn't serious about winning. Mario put up double digit sacks 3 out of 4 years with 43 sacks in 4 seasons. He single handedly beat the Packers. Hes 34th all time in career sacks ahead of some names like Cam Wake, McGinest, Tamb Hali, Trent Cole. But yeah, total bum.
TBD's ideal player is a high motor try hard with marginal NFL talent earning vet minimum who was selected in the 5th round of the draft or later. The resentment for any player selected in the first rounds of the draft or making big guaranteed money is real.
