Grand Canyon: The Lopes lost by single-digits to No. 7 Nevada and to Seton Hall – which beat No. 19 Kentucky. They led Seton Hall by two with a little more than a minute remaining. But they were never in the game against Texas. Grand Canyon is now 0-12 against opponents from Power Five conferences. They became an NCAA Division I program in 2013-14. Only one of those 12 games were played at home in Phoenix — against Louisville in 2016.
Texas: The Longhorns ranked 294th nationally in 3-point accuracy with 30.4 percent coming in. But when they do make them, good things happen. In their last three victories, they hit 11 of 24 (45.8 percent) against North Carolina, 11 for 25 (44.0) against Purdue and 16 of 30 against Grand Canyon. They moved the ball well against Grand Canyon, sometimes eschewing open 3-pointers early in the shot clock to get an even better look.
Grand Canyon is at Northern Iowa for the first time on Wednesday.
Texas faces Providence on Friday in Austin. They’ve met five times, with Texas holding a 3-2 edge. Texas won the most recent game, 79-77 in 2004 in overtime.
