The film does make Landon look very appealing. Almost like he can be a very good b/u with 10-20 more pounds.There appears to be a lot of the Hummer there. But the film (and given it is a highlight film) shows a guy that is willing to take it to the rim and finish with either hand...something we never saw Hummer do. With a decent handle at 6'9", that expands has offensive threat immensely. Mirk showed his finishing ability by just tossing a 4 footer into the net without anything fancy...which seemed to be there at any time if he could convert it at a high percentage.
What we do not see is Landon's defensive ability. And yet, with his movement, and quickness for his size, that can be developed and will be a huge determining factor for him getting minutes.
Overall, there is reason to be very optimistic that he will develop. It all depends on his willingness to learn and his work ethic. Huge potential...much like JJ showed as a frosh....yet more natural. We must remember the difference on the defensive end that Hummer showed from his first to second season as an Illini. It was huge.
