Obviously 2 games does not a career make, but I am seeing a few issues with Rivers that I hope get corrected quickly.
The biggest weakness that I am seeing is he is picking up his dribble. I was under the impression when he was drafted that although he is not an elite athlete, he did have elite handle. This certainly does not appear to be the case. When he is facing the basket he has the shake n bake, stop n go moves to get by most defenders. But when he is faced with a quick guard that can get in to his jersey, he hasn't learned how to create space with his body yet. He also has a pretty weak left hand it seems. As a coaches son, you would not imagine this would be the case. So far this season it seems that every time he gets doubled or even has a defender rotate towards him, he picks up his dribble. As a PG he has got to learn that the one thing he can never do is give up his dribble before he is ready to pass.
The 2nd thing I am noticing is that he seems to have already lost confidence in his jump shot. He had a few openings last night against the Jazz and would not pull the trigger. I know he is not considered a great shooter, but he must take open shots. This will open up other parts of his game as defenders are closing out on him. Also, he does not appear to have a mid-range game either. He must develop a pull up mid range jumper or a floater. He may already have these skills but he hasn't shown them yet.
Wild shots at the basket -- When he is taking it to the hole, he is not actually getting in front of his man. This is causing him to lob up wild shots at the basket with little chance of going in. To be honest, I am perfectly fine with this. It seems like every time he goes to the rim, good things are happening. He needs to keep being aggressive. With experience he will learn how to get the defender on his hip, and not in his chest. He will also develop the strength necessary to finish at the rim. I have also been pleased with his drive and kick game. 6 assists and 2 TO's is something I think we would all take every game. He is going to need to score the ball however.
Defense - He is pretty lost out there. I am worried that after a few more games teams are going to begin isolating against him, in both the face up game and the post.
Overall, Rivers is a little further behind then I expected. Even playing at the 2 while GV is running the 1 he has been pretty ineffective. I still think he will turn out to be a good player for us. He is going to be getting thrown in the frying pan over the next 4-6 weeks while EG is shelved, the play time is going to be great experience for him, I just hope it doesn't ruin his confidence.
