It sounded like, “All day! All day!” as a fan screamed from the stands at the Thomas & Mack Center in the first game of the second day of action at the NBA Summer League on Saturday.

He was really yelling, “All Daye!” as in Austin Daye, Detroit’s first-round draft pick. The “e” in his name may be silent, but his game certainly is not.

It literally was all Daye as the 6-foot-11 forward selected No. 15 out of Gonzaga played all 40 minutes for the Pistons (after playing just 19 minutes on Friday), tying fellow rookie DaJuan Summers for the team lead in points with 19 and also swiping eight rebounds.

“He has a chance to be a real nice basketball player,” Pistons summer league head coach Darrell Walker said. “That’s going to come with age and Arnie [Kander].”

Kander is Detroit’s legendary strength and conditioning coach charged with bulking up the lithe 200-pound Daye the same way he helped pad the frame of Tayshaun Prince when he entered the league in 2002.

Daye is the latest summer league participant to be scrutinized for his skinniness. Last summer it was Golden State’s Anthony Randolph. Two years ago it was Oklahoma City’s Kevin Durant. Instead of questioning his weight, Daye left the packed gym marveling at his length. Standing nearly 7-foot with an even longer wingspan, Daye is the type of guy who can scratch his shins without bending his knees.

Daye, whose father Darren played for the Celtics in the ‘80s, credited his dad for stressing the importance of his all-around game even after he grew from a 6-foot-2 point guard as a freshman in high school to the sky scraper he is now.
