I've attended 30 College World Series, so I have hundreds of stories related to the highlight of my baseball calendar every year. My favorite -- and anyone who knows me well has probably heard me tell it -- centers around Michael Rebhan, who died unexpectedly yesterday at age 51.

Rebhan won Most Outstanding Player honors at the 1990 CWS after earning complete-game victories in the second round and in the semifinals, spurring Georgia to the national title. Both of his decisions came against Stanford and Mike Mussina, who would go on to win 270 games in the big leagues en route to the Hall of Fame.

As for Rebhan, he never pitched another competitive ballgame. Though he had multiple offers from MLB organizations, he also had a wife and two children and decided he could do a better job of taking care of his family as a software engineer. I've always admired that more than the fact that he helped my alma mater (and a bunch of players I had gone to college with) win the CWS.

I enjoyed MLB Pipeline's article on 30 prospects to talk about for 2021. In your estimation, is there one particular prospect from the list who stands out as the next Ronald Acuna Jr., Vladimir Guerrero Jr. or Eloy Jimenez? -- Richard G., Branford, Conn.

The Acuna/Guerrero/Jimenez bar is a difficult one to clear because they're three transcendent talents. One prospect who could belong in that discussion is Rays shortstop Wander Franco, but he's generating so much buzz already that we didn't include him.

With that in mind, here's how I would line up the five best prospects from that story, in which we picked one from each organization. It wasn't easy, because 15 made my initial cut:

1. Matthew Liberatore, LHP, Rays

2. Nolan Gorman, 3B, Cardinals

3. Oneil Cruz, SS, Pirates

4. Kristian Robinson, OF, Diamondbacks

5. Ronny Mauricio, SS, Mets

There's little doubt that Guerrero's bat will make him a superstar. But all those Miguel Cabrera comparisons he draws apply to both his offense and defense.

If there's a knock on Guerrero, it's that he doesn't keep himself in better shape. He has below-average quickness and range at the hot corner, albeit with a plus arm. He can play a passable third base for now but will become a liability if he loses a step as he gets older and heavier.

Toronto has a number of talented infield prospects, and Bo Bichette, Jordan Groshans, Kevin Smith, Cavan Biggio and Co. all can't play up the middle at the same time. Groshans is my pick as Toronto's third baseman of the long-term future and should be big league-ready in 2022, so that's the over/under for when Guerrero moves off the hot corner.

Burnes played a key bullpen role as a rookie, logging a 2.61 ERA in 30 regular-season appearances and a 2.00 mark in six playoff outings as the Brewers advanced to the National League Championship Series. Milwaukee used him as a reliever out of need, but he ranked third in the Minors in 2017 in ERA (1.67) and WHIP (0.95) as a starter. We envisioned that as his long-term role when we placed him at No. 69 on our preseason Top 100 Prospects list and No. 53 on our midseason Top 100 last year.

Burnes relied heavily on his fastball and slider as a reliever, but he'll mix in a few more curveballs and splitter/changeups if he makes the Brewers rotation. His 6-foot-3 build, age (24) and repertoire (92-95 mph sinker, mid-80s slider as best secondary option) are similar to Jack Flaherty's, and Milwaukee would be delighted if he could produce similar results as a starter.

The consensus best all-around hitter in the 2019 Draft, Vaughn has batted a silly .524/.714/1.000 with three homers and 14 walks in his first seven games. The California first baseman seems like a nice match for the White Sox with the No. 3 overall pick in June -- if he lasts that long.

At No. 51, the Mets' Pete Alonso is the highest-rated first baseman on our new 2019 Top 100 Prospects list, and Vaughn is a superior prospect. He projects to be a plus hitter for average power, a combination matched by just five members of the Top 100: Guerrero (No. 1), Padres shortstop Fernando Tatis Jr. (No. 2), Jimenez (No. 3), Astros outfielder Kyle Tucker (No. 8) and Brewers second baseman Keston Hiura (No. 20). Vaughn can't match their defensive value and hasn't proven as much in pro ball, so I anticipate he'll slot in the 20-35 range on our midseason Top 100.
