Former NBA champion questions Knicks' championship credentials

Shumpert played alongside LeBron James for his sole championship run. He knows what it takes to overcome the odds and come out of the NBA Finals as the best team in the world. However, he has missed the mark in questioning Brunson's ability to generate offense out of isolation possessions. 

Last season, Brunson ranked ninth in the NBA for isolation possession per game. He shot 39.3 percent from the field in those possessions, averaging 0.88 points. He is one of the more feared isolation scorers in the East and can strike fear into the heart of a defense. Nevertheless, he's yet to prove he can sustain his offensive heroics during a deep playoff run, where teams have opportunities to adjust their defensive coverage and schemes. 

A high pick-and-roll between Towns and Brunson won't be enough to crack open the defense of the Boston Celtics or Philadelphia 76ers. As such, it will be interesting to see who else emerges as a go-to bucket-getter on the Knicks roster. Because if that weight rests solely on Brunson and Towns, they may be another year or two away from having the right pieces to finally break the championship drought in Madison Square Garden.
