Charlie Jones came off the bench and gave the Gaels a huge lift with unselfish play.
"That guy is just a tough smart basketball player," Clatchey said. "He just does all the little things that don't show up on the state sheet, but they help you win. He's a really good inbounder and a good receiver of the ball because he cuts to the open area and he's a good free throw shooter."
The entire team shoots free throws well and they didn't let down against the Patriots, knocking down 21 of 23 foul shots.
The Gaels started their rally after falling behind 29-19 with 5:55 left in the third quarter, following Rodney Elliot's free throw.
Long hit a pair of free throws and Williams (14 points) followed with a three-pointer and pair of three throws with 1:46 left in the third quarter that cut the deficit to 31-28.
Jones fed Lawrence a diagonal pass from the deep corner and he canned a jumper from 17 feet to cut the Patriot lead to 31-30.
Jones' basket with 3:29 left was the Patriots only field goal of the third quarter and it wasn't until 2:01 was left in the fourth quarter when Stokes ended the field goal drought.
Booth made a field goal with 7:05 left to tie it at 31-31 and Williams nailed a three-pointer that gave the Gaels a 34-31 lead with 6:30 remaining.
They never relinquished the lead and built on it by making 17 of 19 free throws in the final quarter.
"I just wanted to be aggressive," Williams said. "I didn't wanted to go out the way I did in the MIAAs. I wanted to go out with a bang and win a championship. I wanted to give it my all."
Gael players have been giving their all and the school has been rewarded with the most wins in Baltimore Catholic League history (285) in BCL games only.
Clatchey has coached 166 of those victories and trails only former coaches William Wells (St. Frances, 174), the late Ray Mullis (Cardinal Gibbons, 183) and Catonsville native Jerry Savage (Loyola, 190) in BCL victories.
Mount St. Joe's four BCL tournament titles leaves them behind Towson Catholic and Loyola (5 each), Calvert Hall and Cardinal Gibbons (6 each) and St. Frances (7) for most tournament championships.
The Gaels won the BCL regular-season title with a 12-2 record, earning them their sixth league title, which tied them with St. Frances and Calvert Hal,l and left them trailing only Cardinal Gibbons (8).
But, even the tournament crown didn't leave coach Clatchey without some question marks as the Gaels prepare for the prestigious Alhambra Tournament, March 15-17, at Frostburg State University.
"We need to find a consistency level because I'm getting balder and balder," Clatchey said. "We feel very honored to be invited to Alhambra, but that is a couple weeks off and everybody needs to kick back, relax a little bit and kind of get their mind right."
