To shine? Sure, that’s possible. But being the leader of the team? That’s not going to happen. He needs to show consistency, not just one good game. Take a look at Reaves, he was just an ordinary Lakers player, but slowly, he worked his way up to being a starter. He may not be as popular as LeBron or AD, but he’s achieved a lot with the team, even representing them during the FIBA World Cup. That’s the kind of steady progress it takes.
After that game, he might gain the attention of the fans and if he continue bringing that same intensity both in practice and real game he might get that minutes for sure, though it's going to be different when playing with LeBron and AD most likely the design of the play is for both of them, not unless coaching staff will create a play that will let those role players to be more involve with their offense, but, until LeBron continue to design the play inside the game things will be different for those role players and new stars.
It's the same with the Japanese player with Memphis, point guard Yuki Kawamura and he is really that good. However, we are not sure if he can have a spot as this pre-season, mostly they like to expose not their stars and so Dalton Knecht has been given that exposure and the good thing is that he takes full advantage of it.
But not sure if he will be given playing time once we are are in a full mode regular games. It's totally different, it's Lebron and AD's team and then they have a lot of good players as well. Maybe he will be given time to play but I don't expect him to be a regular.
