The NBA gave J.R. Smith a warning - and then a $50,000 fine when he ignored it.
The league penalized the New York Knicks guard again Wednesday, this time for ''recurring instances of unsportsmanlike conduct'' after he tried to untie an opponent's sneaker for a second time in two games.
Smith untied Mavericks forward Shawn Marion's shoe while they were standing next to each other during a free throw attempt at Dallas on Sunday and was warned not to repeat the act by the league office.
Bush league stuff, though I guess you have to admire his nerve:
Coach Mike Woodson had said before Tuesday's home game against Detroit that Smith shouldn't be doing things like that, but the reserve guard then tried it again on Greg Monroe during a free throw attempt - with league disciplinarian Rod Thorn in attendance.
