Though 20-year-old Kristaps Porzingis has impressed with how quickly he's been able to produce, the truth is that the 7-3 Latvian could do even more if he could figure out how to stay on the court.

In the five games before Friday night's 99-92 loss to the Bucks, he picked up five fouls in three and four in another. His five fouls against the Cavaliers in Wednesday night's loss limited him to 21 minutes, a pivotal factor in the Knicks' second-half fade in that game.

Porzingis has been something of a revelation, and the growing pains everyone expected have been all but absent. He got his second double-double Friday night -- 14 points and 13 rebounds in 28:04, along with only three fouls -- and he's averaging 12.3 points and 8.3 rebounds in 24 minutes per game.

"He's a smart player," Fisher said. "He picks up things pretty quickly on both ends of the ball, but the NBA is tough . . . He seems like he's going to be a guy that can defend multiple positions and then offensively do a number of things."

"They still have to put me through some extreme tests . . . [but] I'll be out there within the week,'' he said. "I can't say Sunday.''
