For NBA rookies, summer league merely first step Summer league play started Saturday, and for Winslow and Turner — both still teenagers, neither turning 20 until next March — it might have been considered by some onlookers as a significant first step in their transitions to NBA life. [...] the rookies who knew plenty of eyes were on them were both trying to make it seem like business as usual. Winslow played four positions for Miami, doing everything from handle the ball to play power forward on the way to a 15-point, three-assist, two-steal performance. Turner started at center for the Pacers, shooting 8-for-11 and finishing with game highs of 20 points and eight rebounds. Play in the Utah league starts Monday, and the Las Vegas league — the biggest one of the three, by far — starts next weekend with San Antonio Spurs assistant Becky Hammon becoming the first woman to be head coach of an NBA summer league team. [...] whatever expectations await the rookies, at least there's no circus atmosphere to add to the level of pressure. Winslow said he's valuing summer league to learn the nuances of NBA rules and get used to the longer 3-point line before he'll start playing with the bulk of the Heat veterans in the coming weeks to get ready for the season.
