One coaches in the ACC; the other the Pac-12.

But Mark Turgeon and Tad Boyle have taken near identical roads to San Juan this week, where their basketball teams teams — the 1-1 Maryland Terrapins and the 1-1 Colorado Buffaloes — will meet in a second-round game at the Puerto Rico Tip-off Classic.

Turgeon and Boyle were teammates at Kansas, where they played for Larry Brown. From 1994 to 1997, both were assistant coaches under Jerry Green at Oregon. When Turgeon got his first head coaching job at Jacksonville State, Boyle joined his staff. And he followed Turgeon to Wichita State, serving as associate head coach through the Shockers’ run to the 2006 NCAA tournament’s Sweet 16, which ended in Washington with a loss to George Mason.

Both coaches also have three children and a wife named Ann.

On a personal level, it’s a game Turgeon dreads playing. But on a professional one, he can’t take the court soon enough, eager to set straight so much of what went wrong for the Terps in their 62-42 opening-round loss to No. 16 Alabama, particularly in the first half.

“We were a train falling off a cliff the first half,” Turgeon said.

Maryland shot 18.5 percent in the first half while allowing Alabama to hit 42.4 percent. The Terps’ trio of starting guards combined to shoot 1 of 13 in the period, with senior Sean Mosley finally hitting as the halftime buzzer sounded. Mosley was 1 of 7; Terrell Stoglin, 0 of 5; and freshman Nick Faust, 0 for 1.

Turgeon also chafed at a lapse in defensive effort toward the end of the half.

Boyle, 48, was impressive in his first season at Colorado last year, leading the Buffaloes to a school-record 24 victories. This season’s squad returns just 24.7 percent of last year’s scoring but boasts a tremendous player in sophomore Andre Roberson, a 6-7 guard who led Colorado in rebounding (7.8 per game), steals and blocks as a freshman.

Maryland and Colorado tip off at the Coliseo de Puerto Rico at 6:30 p.m. The game will be broadcast on ESPN3.

In the tournament’s other second-round games, Temple takes on Purdue at 1 p.m.; Western Michigan faces Iona at 3:30 p.m.; and Alabama plays Wichita State at 9 p.m.
