Whether Marvin Bagley will actually be cleared to play at Duke this season remains undetermined. But, just for fun, let's assume the projected No. 1 pick of the 2018 NBA Draft is in uniform and ready to go when the season starts. How will he be?

Great?

Good?

Or just a work-in-progress -- a better prospect than player?

My guess is ... great.

Hand to heart, I really do believe Bagley will be terrific from Day 1. And, by end of the season, I think it'll be clear that he lived up to the hype and established himself as a fantastic prospect and player who looks like the NBA's next great thing. Put another way, I think he'll be the best power forward in all of college basketball.

Which got me thinking.

Who will be the second-best power forward? And what about point guards? And shooting guards? And small forwards? And centers? So, with that in mind, I sat down and made a list. The result is below. Let's call it the Five Best College Basketball Players At College Basketball's Five Different Positions.

Here we go ...

Point guards

Rank Player School Class Height 2016-17 numbers 1 Jalen Brunson Villanova Junior 6-3 14.7 ppg, 4.1 apg 2 Joel Berry North Carolina Senior 6-0 14.7 ppg, 3.6 apg 3 Landry Shamet Wichita State RS Soph. 6-4 11.4 ppg, 43.9 3-pt pct 4 Trevon Duval Duke Freshman 6-2 16.1 ppg, 7.5 apg (HS) 5 Collin Sexton Alabama Freshman 6-2 32.6 ppg, 6.3 rpg (HS)

Explanation: Brunson is experienced, steady, a good-enough shooter and a total winner who is terrific at the free-throw line and thus built to close games. So, I think, he's the best point guard in college basketball. But Berry, the reigning Most Outstanding Player of the Final Four, is a reasonable alternative. If you prefer him, that's not stupid. Shamet could be this season's breakout star. And though I considered SMU's Shake Milton and Kansas' Devonte' Graham for the fourth and fifth spots, I went with Duval and Sexton because, almost every year, elite first-year point guards emerge. Lonzo Ball and De'Aaron Fox were those guys last season. Duval and Sexton should be those guys this season.

Shooting guards

Explanation: It's probably reasonable to go with Trier or Allen in the top spot here. But I went with Trier simply because he was significantly better than Allen last season. He shot it better from the field and from 3-point range. He scored more and rebounded more. So Trier's the pick. But I do think Allen will have a bounce-back season. If he's an All-American, it won't surprise me. Carter doesn't register with casual fans. But he's been a productive guard for a team that's made three straight NCAA Tournaments, including two Sweet 16s. I'm expecting a big season from Brown, who averaged 11.8 points, 5.6 rebounds and 3.2 assists as a freshman. And Diallo should be the nation's best freshman shooting guard, in my opinion. He'll benefit from the time he spent practicing with Kentucky last season.

Small forwards

Rank Player School Class Height 2016-17 numbers 1 Miles Bridges Michigan State Sophomore 6-7 16.9 ppg, 8.3 rpg 2 Michael Porter Jr. Missouri Freshman 6-10 36.2 ppg, 13.6 rpg (HS) 3 Trevon Blueitt Xavier Senior 6-6 18.5 ppg, 5.7 rpg 4 Kevin Knox Kentucky Freshman 6-9 28.9 ppg, 10.9 rpg (HS) 5 Mikal Bridges Villanova RS Junior 6-7 9.8 ppg, 39.0 3-pt pct

Explanation: Bridges and Porter could be listed as power forwards; they each play some small-ball four. But I decided to put them in the small forward category because that's their natural position. And I went with Bridges over Porter -- even though I believe Porter is the superior NBA prospect -- because I think Bridges is just going to be awesome this season. Unless I change my mind for some reason, he'll be my pick for National Player of the Year in the preseason. I could easily see him averaging 20 and 10 and producing countless highlight-reel dunks for a Big Ten champion. Bluiett should end up surpassing the 2,200-point scoring mark for his career this season. Knox is one of UK's next one-and-done stars. And Bridges should have the breakout season a lot of people thought was coming last season.

Power forwards

Explanation: Colson is the only CBS Sports All-American from last season back in school. He could reasonably be placed at the top of this position. But, like I've said and written many times, Bagley is special. So he has to be No. 1 ahead of Notre Dame's leading scorer and rebounder. Williams averaged 11.9 points, 8.2 rebounds and 2.5 blocks last season and should be better in every category this season. Daum is the nation's best so-called mid-major player. He averaged 25.1 points and 8.1 rebounds while leading the Jackrabbits to the 2017 NCAA Tournament. And the fifth spot went to Boatwright, who led USC in scoring last season while averaging 15.1 points and shooting 90.7 percent from the free throw line. He barely edged Georgia's Yante Maten and Michigan State freshman Jaren Jackson for the fifth spot.

Centers

Rank Player School Class Height 2016-17 numbers 1 DeAndre Ayton Arizona Freshman 7-1 26.0 ppg, 15.0 rpg (HS) 2 Angel Delgado Seton Hall Senior 6-10 15.2 ppg, 13.1 rpg 3 Ethan Happ Wisconsin Junior 6-10 14.0 ppg, 9.0 rpg 4 Jock Landale Saint Mary's Senior 6-11 16.2 ppg, 9.2 rpg 5 Mohamed Bamba Texas Freshman 7-0 14.0 ppg, 8.0 bpg (HS)

Explanation: Everything I've heard out of Arizona is that Ayton has been tremendous in offseason workouts. So he should be the Wildcats' next one-and-done star and, possibly, the key to Sean Miller's first Final Four. Delgado averaged 15.2 points and a national-best 13.1 rebounds last season. He's a no-brainer pick for this list. And I can't tell you how much me and some of my friends who are also college basketball writers argued over Happ. Some thought he should be listed as a power forward. But the truth is that he spends most of his time playing what amounts to center for the Badgers. So I placed him on the centers list -- just ahead of Landale, who averaged 16.2 points and 9.2 rebounds last season. And the fifth spot went to Bamba, who should be a one-and-done shot-altering standout at Texas. He edged USC's Chimezie Metu, who averaged 14.8 points and 7.8 rebounds last season.
