I have a bad feeling about extending Johnson.
I just don't care for him as a player at decent salary. Bad defender most of the time, too small to play 4, not skilled enough to play 3. Hustle player without hustle stats, seems to get fatigued too easily. Hate seeing him defend the ball handler in the pick and roll, doesn't get skinny to get over, doesn't fight to get under.
Hope he's traded, not too optimistic about his future. If Primo is as good as people like to hope, and Vassell continues to show, then in a future 5 man lineup of Poeltl-Johnson-Vassell-Primo-Murray, Johnson will be the weakest link and position to upgrade.
He's not close to the Bridges guys for instance but will probably want to paid like he is.
