I agree with Dunkin Dan. When I brought up the fact that Ingles/Exum aren't really producing enough to justify their minutes, I say it with concern for them - Not as some sort of tall poppy hater.
The truth is they aren't producing right now. Obviously that needs to change or they face the risk of teetering their way out of the league. Exum has a bit more time up his sleeve than Ingles does. Ingles has been a good role player, but if for some reason the Jazz cant keep him next season, will anyone else pick him up on his current production? I wouldn't be guessing so.
I am a huge fan of Joe Ingles, but in the end of the day, he needs to produce to stay. He needs to be willing to take a few more shots and to do more than just be a good presence and head on the bench if he wants more time in the league. Facts are facts. We are talking about someone who is going to be 28 this year. NBA chances start wearing thin when you approach 30. Joe can definitely do it.
As for Exum, he is dancing around being the player he could be. His outside jump shot has proven to be much better than predicted. His defensive effort is also very good. As is his passing. However, he is doing little of the one thing everybody saw in him. Penetration! He can hit a three all he likes, but until he makes the defence in the key pay, he is only going to realise a small amount of his potential. He is doing "ok", considering he is 19 years old. But seeing as we don't have a crystal ball, I see his trajectory going like this. He either becomes creative, gets to the ring, looks to score more, bulks up, becomes a genuine NBA player/star. Or, he continues playing like he is. He doesn't ever really get the guts to take it inside... rather he perfects his outside shot. He finds himself in the bunch of hundreds of other players who can pass and hit the three. And he becomes either a bench role player, or ends up playing his career out in Europe.
Both Exum and Ingles have shown signs of being very good. Both do deserve time invested in them. But I think fans and administration will start expecting more from them soon. There are a lot of great players who would love to take their places.
