Not really. The arms are up to block the pass. You can hit much harder with your arms low and then moving them up as you explode into the QB. They would never be over your head. You clearly never played football.
Read my original post again.....nowhere did I have the rusher with raised hands.....only extended outward as he reaches the QB.
You are right in that the defense often raises their arms to block passes, but that isn’t germane to this scenario.
