I don’t think Davis does too well as a 3-4 OLB edge. Yes he can rush the passer but his ability in that aspect is from his speed, ability to slip thru traffic, etc, not really a pass rusher. I mean I could possibly see him playing SOLB in the base then off ball in the nickel but I don’t think with DD getting older they want him constantly banging at the line of scrimmage, plus the benefit of the 3-4 is not knowing which OLB they’re blitzing, with DD it would take that aspect away, DD isn’t beating tackles on the regular. Not saying it couldn’t work, just saying it isn’t optimal.
