The reason why I say this is he has natural ability to get to the ball carrier, rather it be a bull rush or a swim move, whatever.. all I know is he's got a knack to get to the carrier and even if he doesn't know the playbook yet he has intangibles you just can't coach or teach. He needs to be out there on every down as he is a tremendous athlete with a motor that won't quit. Having him come in on 3rd downs is such a gimme to the opponents defense.. it spells out rush the QB on the ends.. so again Iowa is basically giving up a play here as the D knows exactly what's coming.. I am no coach or never claim to be but common sense tells you when 94 comes in the offense knows what's coming and that's heat off the edge or the middle .. just my 2 cents!
