Look at it this way, Aldon smith only did 20 on the bench himself at the combine which isn't very mind-blowing. Guys with arms that long typically don't do too well on the bench from what I recall but that doesn't mean that their power can't translate to the field better than in a combine workout. I once saw Albert Haynesworth throw Jamaal Brown on his back in 2007 but he only repped 17 on the bench at the combine.
