You seem to be remembering incorrectly. Truth is, LK only had a competent offense for a year or two, when he had 3 legit NBA starters on his team. It was the Jakob PnR, or pass around the perimeter and ask the shortest guy on the team to shoot a contested desperation bomb at the buzzer.
LK was always a s**tty Xs and Os guy. Terrible at breaking the press. Terrible at coaching half court offense.
Smith is clearly the better coach. Recruits just have no reason to come to SLC.
