The tone some of you guys take... embarrassing.
He had a good game, be happy for a second. Jeff is a player who can get hot. That's just how it is. He isn't a reliable big time scorer.
And he is a player who plays within the team, is effecient, defends really well now. He just is never going to reliably score up to 20 points.
Like Monk mentions above, players to hope he is like are Batum and Deng. The issue for the comparison is that Batum's passing has really improved, but still, they compare and make similar money, though Batum makes 2 million per year more. And Deng is a more reliable scorer (without the highs though, and Jeff is a better shooter) and Deng makes about 5 million more per year.
Now I understand needing to shed him rebuilding because you need the space under the cap. But if you can make it work, he's a very good complimentary player. He just can't really be relied upon to be more than that scoring wise. Just like say, Deng, who hasn't been as good of a scorer as it seemed he was going to be. But Jeff makes a lot less, and is a great three point shooter and spaces the floor.
I still think Houston is crazy for not making more of a push for him (though maybe they have). He'd be really great on a team like Memphis or Houston.
Basically, I'm not sure, a lot of times, anyone compares players around the league and ones they are being super critical of... if Deng is making what he is making and people don't hate on him but Jeff makes a good amount less and takes all this flak, we just aren't paying attention to value on the market.
