CHATHAM, NJ - When Mac Bredahl scored five points in the final 4.4 seconds of the first half, draining a 3-pointer as the buzzer sounded, Chatham walked off the court with an incredible 41-point boys basketball advantage over Mount Olive with the senior guard leading the way with 21 points.

There was little room left for an encore, but senior guard Jack Rooney did his best, scoring 14 points in the third quarter to give him a career-high 29 points as Chatham opened play in the Cougar Classic on Tuesday with an 87-40 win in which it dropped in 16 3-point baskets.

Rooney capped his night by knocking down three 3-pointers in the final 1:14 of the third quarter, equaling his school record of eight 3-pointers made in a single game set two years ago.

Jack Rooney talks about his hot shooting night with Ryan Doherty

Rooney had set the school record for 3-pointers in a game when he hit eight and scored 26 points in a 2016 state tournament game against Iselin Kennedy.

Rooney missed the first shot he took in the game but didn't miss many more, sinking 10 of 13 shots (76.9 percent), including 5-for-5 in the third quarter. Bredhal made eight of nine shots in the first half and shot 80 percent for the game (8-for-10). 

The Cougars (4-1), winners of four straight, scored the first 17 points of the opening quarter with Ryan Doherty (16 points), Bredahl and Rooney hitting 3-pointers, Bredahl converting a three-point play and Doherty capping the spree with a 3-pointer. After a three-point play by Lance Johnson interrupted the run for Mount Olive (0-5),

Chatham closed out the period with Daniel Baker's putback, Rooney's 3-pointer from the top of the key, Bredahl fast-break layup off a Rooney pass and Doherty's running one-hander. That made it 26-3. Bredahl went off for 13 points in the second quarter, culminating the half with a drive to the basket with 4.4 seconds showing and a steal of the inbound pass that he turned into a 3-pointer from the corner and a 51-10 Cougar lead.

"We moved the ball well as a team, which opened it up for all of us," Bredahl said. "We were hitting our shots, which helps. We shot the ball great today. I think that has a lot to do with us incorporating everyone into our offense, moving the ball around and getting everyone touches."
