Readiness is the million dollar question. Ryan was very good, but definitely not ready as a freshman. He had the height and skill, but not the strength or explosiveness. McClure wasn't explosive enough or skilled enough to excel as a freshman. To me, he needed to be taller and or stronger at his ability level or more skilled or explosive at his height.
That's why I think Kyle has a chance to contribute right away. Similar body and athleticism as McClure, but way longer. Maybe a touch better shooter as well. Similar height and overall skill level as Ryan, but stronger and more aggressive (hopefully) as a freshman.
If he can't contribute right away, I hope everyone is patient with him. He is a really good kid, good student, hard worker, and very likeable.
