Burr-Kirven has 31.88 inch arms. For reference, Keuchly has 31.0 inch arms. Burr-Kirven probably has a game closest to Keuchly, albeit shorter in height. I never really cared for Keuchly as a head up toe to toe backer for the middle and thought he would have been better being able to roam more free as a WLB, but that's what we're talking about for Burr-Kirven, or at least I am.
Point is, one is 6'2 238 with 31 inch arms and one is 6' 230 with 31.88 inch arms. Both lead CFB in tackles.
Yes, you read that right, Keuchly is the name that he is despite being underweight with t-rex arms. It's not a death sentence apparently, so it should remain considered for Burr-Kirven. Especially since Burr-Kirven beat his 40 at 4.56 and his 3 cone time at 6.82.
