It’s not a coincidence. It’s more like a common denominator.

When either Myles Cale or Sandro Mamukelashvili plays well, Seton Hall usually does, too. When they are both productive, the Pirates usually are, too.

“When one of those two guys is playing well offensively for us, it makes life a lot easier for Myles Powell,” Seton Hall coach Kevin Willard said in a phone interview. “It just opens things up for us a little bit more.”

Of course, when the sophomore starters struggle, so does Seton Hall (12-6, 3-3 Big East), which has hit its first extended speed bump of the season.

In this recent stretch of three losses in four games, neither Cale nor Mamukelashvili has played well, each scoring in double figures just once. Neither was a factor in Tuesday’s turnover-fest at Providence. The 6-foot-10 Mamukelashvili battled foul trouble and committed four turnovers. Cale fouled out after scoring nine points on 3-of-7 shooting. With neither able to get going, the Friars focused on Powell, limiting the Big East’s second-leading scorer to 12 points, a season-low in conference play.

“I think offensively, what you’re seeing from the young guys is a typical roller-coaster from freshmen to sophomores,” Willard said as he prepared his team to face DePaul Saturday night in Newark.

“They’re all putting great work, they all have great attitude. Because we’re young, we’re missing shots, and that frustration is leading to a rushed turnover the next possession or a breakdown defensively we weren’t having. But that’s part of a young team.”

So is learning how to win on the road. Seton Hall has already played four games away from the Prudential Center, losing three times. It has also played six league contests, tied with St. John’s for the most in the conference, and that has limited practice time. Willard believes that has contributed to his team’s recent problems, highlighted by the 22 turnovers against Providence.

“I think when you don’t have time to practice, and we’re still a young team — everybody forgets that sometimes — you don’t have time to find a rhythm and you get a little sloppy,” Willard said. “I think a lot of our turnovers the other night came because we haven’t been able to be as sharp as we can by practicing.”
