New York Knicks starting center Mitchell Robinson took to Instragram to complain about his role in the team's offense. It wasn't the first time Robinson has taken to social media to vent about his role this season.

Robinson wrote: "Tired asf of just being out there for cardio fam like I want to play basketball to really just wasting my time and energy (facepalm emoji)"

Despite the Knicks rolling to a 123-107 victory at the Portland Trail Blazers, Robinson was unhappy. He played 21 minutes and took just two shots. Backup center Isaiah Hartenstein played 27 minutes and also only took two shots. But Hartenstein was more involved in the offense, as he dished out four assists.

New York re-signed Robinson to a four-year $60 million deal this past offseason. The Knicks also added Hartenstein for two years and $16 million last summer.
