First off, thank you El Ellis. Good luck to him. Wish him nothing but the best.
In my opinion, Ellis not coming back is a good thing. Speculating here but I think Ellis was told and knows he will not be the primary PG next year. He may just want a change of scenery as well.
The dynamics of this team (all teams really) with the guys KP is bringing in is going to be completely different. Much better players coming in. Clark is a much better guard and overall player. As long as Clark is good mentally, and I think he will be.... fans will really like his game. He can shoot at all levels and is a much better decision-maker at guard. No way Ellis can keep the same role with the guys coming in.
