From NBC Sports w/ NBC Sports' comments:
Ersan Ilyasova is signing with the Jazz for the rest of the season, according to Adrian Wojnarowski. It's not a 10-day deal so the Jazz are committing to Ilyasova, who instantly gives them improved frontcourt depth with the ability to spread the court (36.5% from deep for his career). The veteran's arrival shouldn't have a big fantasy impact, though, as any minutes he earns should come at the expense of Georges Niang and Juwan Morgan. Ilyasova averaged 6.7 points in 17.0 minutes per game over the past two seasons in Milwaukee, which sets expectations while Utah's roster is healthy.
