The cards are still out on T.J. Warren. In his limited playing time this season, he showed flashes of promise, but it will take more for him to become a more regular part of the rotation.
It is always hard to grade guys who don't play very much. And despite the best hopes of the fans, and likely the front office, Coach Jeff Hornacek did not seem to think T.J. Warren was worth of consistent playing time early in the season.
Warren played 25 of his 40 total games played after February 8th. He also played 480 of his roughly 600 minutes during that time, or roughly 80% of his overall minutes.
