Foulland had one of the best games of his Bucknell tenure, recording 20 points, six rebounds, four assists and a career-high-tying six blocked shots. He kept the Terriers' red-hot center Justin Alston, this week's Patriot League Player of the Week, to two field goals and eight points. Thomas added 15 points and seven rebounds.
Meanwhile, Bucknell's backcourt pairing of Kimbal Mackenzie (17 points, four assists) and Stephen Brown (14 points, five assists) combined for 31 points and nine helpers. Freshman Bruce Moore came off the bench to record nine points, three rebounds and three blocks, and classmate Avi Toomer had another good defensive game on Boston University star Eric Fanning, who was held to eight points and did not attempt a field goal in the second half.
"It is a great accomplishment to win the regular-season title, but our guys are hungry for more," said head coach Nathan Davis. "This was a tremendous effort today. The guys played like they prepared for the last two days. We had two very good practices leading up to the game, and that is the effort that it's going to take to get us where we want to go."
Playing on the road with first place on the line -- Boston University (16-12, 11-5 PL) would have pulled into a tie for first with a victory -- the Bison shot 58.2 percent from the field and hit 12 of 22 from 3-point range. The Bison had 19 assists on 32 field goals and went 10-for-13 from the foul line.
At the other end, Bucknell equalled a season high with nine blocked shots, all from Foulland and Moore, and held Boston University to 40.0-percent shooting. The Terriers were 4-for-16 from the arc.
Leading 39-32 at halftime, Bucknell burst out of the locker room on a 26-7 run over the first nine minutes. Foulland set the tone, rejecting Alston's shot at one end and then running the floor for a transition alley-oop jam off a pretty lob from Mackenzie. One possession later, Mackenzie chased down his own missed 3-pointer and flipped it in to push the lead back into double figures.
The play of the game came at the 14:42 mark. Brown lobbed a pass into Foulland with three defenders swarming him. Foulland had a one-touch kickout to Moore on the left wing, and Moore buried the 3-pointer to make it 55-36. A Toomer transition layup, a Mackenzie 17-footer and treys by Thomas and Brown capped the run and gave the Bison a stunning 65-39 lead.
The Bison went 3:33 scoreless, but they conceded only five points in that stretch, all on free throws. Brown ended the mini-drought with another triple, and Bucknell saw out the 20-point win from there.
Bucknell led by as many as 12 in a fast-paced first half. A 10-0 run, launched by 3-pointers by Mackenzie and Thomas, gave the Bison a 14-5 lead. A John Azzinaro 3-pointer and two Thomas free throws stretched the margin to 21-9.
The Terriers got back in it with a 9-0 run, pulling within 30-28 on a Cedric Hankerson 3-pointer. Thomas put an end to the run with a long 3-pointer. The Bison then closed the half with a Foulland dunk, a Brown 18-footer, and a defensive stop to go up 39-32 at the break.
Kyle Foreman scored 16 points for Boston University, which had its four-game winning streak snapped. At 11-5 in the league, the Terriers will now have to hold off Navy and Lehigh, both 10-6, for second place. With Loyola's loss to Colgate, Boston University has assured a top-four seed and a quarterfinal home game.
Bucknell has now captured recent Patriot League regular-season titles in 2011, 2012, 2013, 2015, 2016 and 2017. The first five in that run have been outright (no ties) titles. With a two-game lead over Boston University with two regular-season contests remaining, the Bison can make this one an outright title as well with one more victory or one more Terriers' loss.
This is Bucknell's 11th regular-season title in the 27-year history of the Patriot League. No other school has more than five.
Each of Bucknell's final two games will be at home, starting Wednesday against Lafayette. The Bison close the regular season on Senior Day against Navy next Saturday at noon on CBS Sports Network.
