You didn't get good grades in school did you, your reading is off and your math wouldn't pass 3rd grade level.
Where did I say anything about a second LBer ? Did you skip some meds or what ?
Crazy
I can't believe I actually have to explain this.
Mafe is an edge player, which in the 3-4 is classified as an OLB. Barton is an ILB.
If you put Mafe as a "fourth lineman" in a traditional 4-3 over and remove Barton, that leaves you with 2 LBs total unless you sub in a third. You've taken away one LB by putting them as a 4-3 DE (a complete miscast for a player you also advocate for moving to MLB, which... wtf?) and have benched another.
Ironically, you're advocating for what the team
literally already runs in nickel.
