Definitely did not improve the athleticism situation down low. Sydney Curry would have done that but they jettisoned him and well he's a JUCO and you never know how JUCOs will pan out.
That said Dave was always going to start and he is simply not a great athlete for his position. Love him, wish him the best etc but that's just the truth. Same thing for JWill. JWill is a great rebounder though which we will need.
I think the key that you mentioned is skill and well, ball handling. Harris just wasn't quite ready most of the year last year. You could tell he was coming on late. He's not a scorer but the offense flows with him in. Remy has a lot of skill too. Bobby you can see why the staff loves him, under control, great ball skills. He will be the next great PG for Bill I would bet a lot on that. We went from 0 to 4 quality ball handling guards (it's not like Yesefu was bad when he was in).
Now next year, we could be a lot more athletic. Dave will depart, JWill will depart (barring a drastic change of heart). There are starting spots up for grabs. As the class stands right now, KU has some electric athletes. Udeh is nearing 7 feet. Needs polish offensively but an absolute monster on the glass and blocking shots. Zuby I am extremely excited for. Great on both ends at this stage. Gradey is very athletic too.
