Dynasty: Franklin Arias. The FanRanked staff dynasty board has Arias ahead, Arias #46 and Vries #61, but the expert consensus has Vries ahead (#78 to #111). The community disagrees, leaning Vries, FRV 72.5 to 53.0.
JD on Franklin Arias (Oct 21, 2026): I didn't just want to assume that I should be ranking prospects by their industry average slots, so I've been taking deep dives on every prospect that was in consideration for the top 50. I came away from that ULTRA-hyped on Franklin Arias, and I would hear arguments to have him number 1 overall. I'm not surprised the Red Sox were willing to get rid of Marcelo Mayer knowing they had this demon waiting in the wings. Arias tore up two levels of the minors this year, slashing .323/.406/.557 and hitting 25 homeruns across 520 PA. Potentially even more impressive were his swing decisions, with only a 14.2% K rate vs a 10.2% BB rate. For someone who put up this kind of power in the upper minors, its a rare skill set to have this combination of power, patience, and contact quality. I'll be honest, the swing is the one thing the concerns me. This is 100% an eye test take (so take it with a grain of salt) but the swing looks like it can get too long and loopy, and I'm not sure how it holds up at the big league level. It's one thing to rely on your raw athleticism when you are in the minors and velos and breaking balls aren't as good, but at the big league level if you have to cheat to catch up to velocity you are going to get exposed. I am really splitting hairs here, so don't let it dissuade you from treating Arias like the high quality asset that he is. Just don't be surprised when these elite K rates regress at the big league level and the average drops with it. One final note for what it is worth: Arias has the best 7 year projection of any prospect we track. A 2027 debut would be electric, and would expect him to see him after the ASB if things go right.
JD on Leodalis De Vries (Nov 4, 2026): Here is what I said when news first broke about De Vries' shoulder surgery: "Really brutal news for Leo that he will be out for 8 months with shoulder surgery. Luckily it's during the offseason and he's so young and it's not crucial that he gets a ton of reps right now. It would be nice to see him knocking on the door of the big leagues next year with a really strong spring and start to the 2027 season. I imagine this takes any hope of a 2027 debut as a 20-year-old out of the picture but still leaves the chance that he makes his 2028 debut as a 21-year-old in play. I like what Sebastian Walcott has been able to do coming back from injury so I'm hopeful that Leo will take the time to develop, get stronger, and come out of this better off in the long run. Not selling if I own him here." Nothing has really changed since then, except me diving into some of the other prospects that I think are more exciting from a fantasy perspective. With no injury he's still probably top three for me, but for now I think he's a very strong number seven overall prospect and can earn back his top three status if he proves he's fully healthy during the 2027 season.
