Will Barton's contract for 14-15 became fully guaranteed on Thursday, which puts the Portland Trail Blazers' roster at 15.

Barton, whom Neil Olshey selected with a second-round pick in the 2012 NBA Draft, will make roughy $915,000 next season.

"Will has improved as much as anyone on our roster as a player and a professional," Olshey told The Oregonian in an email. "Having the third year of his contract guaranteed is a validation of his efforts and his value to our organization."
