Fred Hoiberg would bring credibility and NBA experience to the Knicks.
Over his 10-year career, he played and learned under coaches like Larry Brown, Tim Floyd, Flip Saunders and Kevin McHale. And since becoming the head coach of the Iowa State Cyclones, he's built a program that has risen into the upper echelon of the Big 12.
Hoiberg's offense is predicated on spacing, ball movement and taking advantage of mismatches: three things that have plagued NY this season. As seen in the video above, Hoiberg has designed a few basic sets to launch the offense out of transition that his players can play out of without being too restricted.
The "Hold" action, as seen in the beginning of the video, would be beneficial for Carmelo Anthony to get an easier post up opportunity than what he's used to.
Normally, Melo will come down the court on one side and get right into the post. By starting Anthony on the opposite end of the court, and bringing him to the block off of a screen, there's a good chance he could either catch the ball with minimal defense present and score right away, or he could catch the ball on the block, watch the scrambling defense rotate and dish it out to the open man.
Spacing is important to Hoiberg and his offense because it sets up the three-point shot, which has been the catalyst of his Iowa St. teams. Good spacing with proper dribble penetration and unselfish ball movement usually leads to open shots, which was a strong point for the Knicks last season.
The Cyclones website has a great video on Spacing 101, which features Fred Hoiberg and associate head coach T.J. Otzelberger, that I can't embed but recommend watching, here.
