About No. 7 Arkansas

Mike Anderson has the Razorbacks back in the NCAA Tournament for the third time in four years. His team is led by Jaylen Barford, who is averaging 18.0 points. But the player to watch is Daniel Gafford -- a 6-11 freshman averaging 11.9 points, 6.2 rebounds and 2.1 blocks. He's a future lottery pick who destroys rims. He makes the Razorbacks exciting and dangerous.

About No. 10 Butler

The Bulldogs are led by first-year coach LaVall Jordan, who has put this program into the NCAAs for the 10th time in 12 seasons. Kelan Martin is the star to know. Butler's big wins this season over Ohio State and Villanova make them a tempting second weekend pick.
