Actually I think you will see Jackson (a true plus athlete) replace Jeffries for the athletic side of the game.
I expect we will see a starting line up of Igbanu, Horne, Korita, Scott, and Joiner. Jackson will come off the bench for any of the three guards. Falokun will be the big man sub, and will let us go athletic with Jackson and him on the floor.
We need outside shooting. Which Jackson needs to add to his game to become a bigger version of Dante Swanson. We need Scott to become a consistent scorer and not disappear.
We need another post to give us 15 or so minutes grab rebounds, protect t the rim. We need another guard to step up, preferably a strong ball handler who can make open shots.
Finally we have to become physically and mentally tougher. Korita talked about work and effort and the need to have more in the post game interview. I like that attitude.
