I mean, he is another pass rusher. The Bears pass rush was actually pretty decent today, despite not any sacks before garbage time. Wasn't horrible last week also without Mack. Irvin would be worth it to add another pass rusher to the mix, maybe rejuvenate Mack for the 2nd half push, and to keep him away from other contenders. But honestly, I don't think he's really necessary. Mack, Floyd, and Lynch are enough when added to a good 4-man rotation at DL (Hicks, Goldman, RRH, Nichols), and I'd like to see more of Isaiah Irving. But I won't complain about an upgrade at any position. Wouldn't claim him on waivers (and pay his $4M salary), but if nobody claims him I'd imagine the Bears would be a preferable spot for him. \ dont disagree at all. However, the idea of two former Raiders helping the Bears win the division as Gruden and co continue to spiral into hell would be sooooo much fun
