Bold prediction time: Mondesi won't be a thing in 2021. Mondesi showed last year that he wasn't worth grabbing in the first three to four rounds of your draft, yet here we are again, with Mondesi going off the board 40th overall per FantasyPros' ADP. He's not a complete zero at power, but you're drafting him for speed only, essentially. If you look at his xwOBA (6th percentile), xSLG (16th percentile), and xBA (14th percentile) and pair that with his 29.8 K% and 4.3 BB% (both bottom 6 percent of baseball), what's to like? Oh, that's not to mention that he's recovering from offseason shoulder surgery. Unless you're in a big tournament-style league where you need to look for the splash play, avoid Mondesi this year and find your steals elsewhere where you don't have to make quite the investment.
Mondesi had a ridiculous 43 steals last year but he did it in just 416 at-bats. If he can stay on the field for a full season, 60 is not only a possibility, but likely. Add in 15 homers and we are talking about a potential first round value, albeit one with great risk.
