I was not able to watch all that much of these two games, but I think I saw enough to get the idea. With the 2-way for Davison now official, plus Walsh and Champagnie signed (albeit Champagnie is NG), that means the remaining players need to beat out Champagnie or maybe Kornet in order to make the team. We do still have 2 more 2-way slots.
I did not see anyone out there on the Celtic's SL team that was better than either Champagnie or Kornet. Udoka Azubuike looked a lot better in the second game than in the first, but I am not sure he is better than Kornet. If he would take a 2-way, I would definitely offer that to him, he is much better than Kabengele. He absolutely has an NBA body and athleticism but not enough touch or feel for the game right now. I don't think Olek Balcerowksi is ready for even a 2-way. And all the rest are just like hundreds of other possible 2-way players. Some of them are close but really nothing special, nothing you couldn't pick up at any time at any point of any season.
Walsh did not have a good second game. You can see he is an NBA athlete, but still raw. Champagie looked much better in game 2, more what I remember of him from last season. He has some skill and athleticism. I see some potential there, but he is not close to being a player who would actually play other than garbage time. I would say he is still on the bubble.
