The Tigers finished 5-0 under coach Tim Fuller, who filled in for Frank Haith as the head coach served an NCAA-mandated suspension. Haith will return to the bench for the team's Thanksgiving matchup against Northwestern in Las Vegas.
Missouri (5-0) scored 13 of the game's first 17 points and never trailed en route to winning its 22nd consecutive contest at home and its 77th in a row against nonconference opponents at Mizzou Arena.
Missouri's lone returning starter from a 23-11 season, Brown shot 7-of-12 from the field and 5-of-8 from behind the arc. The junior guard joined the Tigers for the second half of last year after transferring from Oregon, where he only played two games.
Missouri made 50.9 percent of its shots and took a 47-34 halftime lead, but IUPUI hung around, narrowing its deficit to 70-61 with 6:39 left on a jumper from Chiles. Missouri's Clarkson then scored the game's next five points to give the Tigers a 14-point lead with 4:13 remaining.
IUPUI's Chiles averaged 19.2 points per game entering the night to lead the Summit League, but his 12 points were his second-lowest output of the season. McCallum and Justus Stanback combined for 25 points off the Jaguars' bench, which outscored its counterpart 25-9 for the game after failing to register a point in both of IUPUI's last two games.
Picked to finish last in the eight-team Summit League after a 6-26 campaign a year ago, IUPUI lost 63-61 to Northwestern on a last-second shot Friday and -- with the loss tonight -- fell to 0-6 against teams from the Southeastern Conference.
A season-low attendance of 6,065 watched Missouri shoot 8-of-19 from 3-point range after only making two of 14 attempts against Gardner-Webb on Saturday. The Tigers' campus is on Thanksgiving break.
The game marked the second contest for both teams in the Las Vegas Invitational, but it had no impact on the outcome of the tournament. The schools will travel to Nevada for games on Thanksgiving.
