Anderson was around 50th in Keith Law's rankings and he was 52nd in an analytical-model based big board by someone on MLB draft twitter that was just hired away by the Cubs, Mason McRae (his big board is no longer public). Anderson doesn't strike out and had really strong EV metrics.
I actually found that to be kind of an encouraging pick depending how the rest of the class shakes out. Thus far, there has been a change in draft philosophy. I probably wouldn't have picked Clark, but that wasn't out of left field- he was an easy top 5 prospect in this draft and would have gone #1 in a number of drafts. He's a great prospect with high upside and there is an argument for him over Langford because Clark is sticking in CF long term and those guys are rare to find. He could be a genuine two-way star whereas that wasn't very likely with Langford. Langford was a safer pick. At the end of the day, though, the player development aspect is the most important thing.

"Outside of a fringy batter’s eye, Anderson’s offensive profile is really good. He has juice and a 106 90th percentile EV on top of a 110+ batted ball. He’s running a 94 mph average EV, he’s never had issues with strikeouts and he seldomly whiffs at pitches in the zone. He hasn’t had a great season in college up until this spring, but the pitch-level numbers have suggested he’s always been good. You’d like to see him swing less, chase less, and therefore walk more, but it could be an area of improvement for a pro ball dev staff. He’s hit two-thirds of his batted balls over 95 mph, it’s real power and he’s not giving away contact to get to it. He’s running a 4% walk rate though. Above-average defender at third. He was one of the better hitters this summer on the Cape and he walked much more. Looking like a late day one profile that model-driven orgs will have an eye on."
