He probably won't be a 3 time super bowl champion like Ted Johnson, and he also probably won't spend any time doing that hybrid 3/4 thing that Terrence Jones did. Bam is strictly a post player who will probably develop a little bit of a jumper for the league while at UK.
So yeah, Jones had more perimeter skills, but also wasn't as strong or brutal as Bam - totally different functions on the court. Jones would wander off to his own planet, sometimes, too - while Bam is known to have a nonstop motor.
