re: I get the feeling BK does not give the effort that O did in recruiting and it shows

I think you have to consider the two coaching philosophies here. One, Coach O, not known to be a developer of talent, relies solely on the athletes ability to help and contribute right now. His skill set needs to be so good that he can step in and contribute right away. This player may or may not get better over the course of a college career. This is solely dependent on the kid and his position coach.

Kelly, on the other hand, has a vision, thinks more strategically. He knows his system, and he knows what type of kid fits into this system. It may not be the flashy, egotistical type right out of high school. He knows that if the kid checks a few boxes, that he can be developed in 1 year to be a contributor.

Now, if the very best player, the #1 ranked kid fits his mold and projects to work well in his system, then I'm sure Kelly is the type to go all in on a kid like that.

Wasting capital, time, and energy on a kid that is a stud, but doesn't fit in your system is an exercise of futility.
