Each day, some of our college hoops experts discuss the biggest issues, trends and themes in and around college basketball.

1. Sweet 16 games tend to be close. So, with a chance to move to the Elite Eight on the line, which player left in the NCAA tournament field do you want taking the last shot?

Andy Katz: Put the ball in Jerian Grant's hands and let him make a play. The Notre Dame guard is the best closer remaining.

C.L. Brown: Plenty of players have made big shots during the regular season, but I'd want the only player who has done it with the stakes at their highest in the tournament. That would be Kentucky's Aaron Harrison, whose 3-pointer against Michigan vaulted the Wildcats into last year's Final Four. And his 3-pointer against Wisconsin put them into the title game.

Myron Medcalf: Probably Fred VanVleet. He's a gamer, and he's been great throughout the early stages of the NCAA tournament. I want the ball in his hands with the game on the line.

2. On the other end of the floor, who is the best perimeter defender left in the tournament? What about the best post defender?

Katz: I wouldn't mind having Gary Browne of West Virginia pestering the players on the perimeter. And Willie Cauley-Stein is the one to block shots in the post. He's tremendous on the weak side help.

Brown: For the perimeter, Arizona's T.J. McConnell is annoying enough -- in a good way of course. He's got the most steals per game of any remaining player. In the post, it has to be Cauley-Stein. He's versatile enough that even if he gets caught in a switch off a pick, he can still defend a guard.

Medcalf: I'll take Gary Bell Jr. as the best perimeter defender. Gonzaga is playing the best defense of the Mark Few era, and Bell is a big part of that. He's versatile enough to guard point guards, small forwards and even centers occasionally. He's a critical component for Gonzaga. And Cauley-Stein is the top interior defender (one of the best perimeter defenders, too). He's a special defender in the paint.

3. You can only have one on your team, but which of the big three big men -- Wisconsin's Frank Kaminsky, Duke's Jahlil Okafor and Kentucky's Karl-Anthony Towns -- are you taking on your squad?

Katz: Tough call. I may go with Towns. He can defend multiple positions, and his offense continues to develop.

Brown: Jah rules. Get it? Like the rapper? Oh, never mind. I'll take Okafor. As a defender, he still has a way to go. But offensively if he's being defended straight up, it's as good as a guaranteed basket. His footwork is crazy. His post moves are limitless.

Medcalf: I'm taking Towns. He's arguably the most talented -- if we're talking raw talent -- of the three. And he has the best combination of offensive and defensive capabilities among the group. It's hard to shine when you're playing next to seven other McDonald's All Americans. But Towns is in the same talent stratosphere as Okafor and Kaminsky. Plus, he has the highest ceiling within this trio, too.
