I'm bored so started digging into stats for this year's draft. A lot of college OFer's are expected to go in the middle to late first where we have two picks so though I'd breakdown those positions. The main case I'm going to make here is why we shouldn't be drafting one of these guys in the first, which is a piggyback onto my previous comments about college hitters not being as safe as one might think. I've included some advanced stats that basically categorize into swing decisions, contact ability, and slugging capabilities and highlighted red (bottom 40th %), orange (41-80th %), and green (81+ %) just to help visualize. I also have the hitters in roughly the order they are projected to go.
First, Gracia appears to be legitimately ranked as the best of these hitters with no real holes and both great swing decisions and batted balls. However, he will almost certainly be gone before we pick (likely top 10). He serves as a sort of baseline for what you are looking for because if you look at just his AVG, OBP, OPS, etc. he may look similar to a lot of the other first round OF's.
Burress is....ok. He gets dinged a big for being a righty though. However, Curiel looks like a better bet if you are determined to take one of these guys in the first with his only issue being pull air %, which we have seen guys capable of developing over time (see Raleigh last year) plus he is more likely to stick in CF.
The other guys projected to go in the first, despite their greater averages, OPS, etc. have some serious questions. They all make varying degrees of poor swing decisions and whiff at a high rate. I'd avoid all of them.
Now the case for not taking any of these guys is in the last 3 hitters. Beck's only hole is some chase, but I will give him a little slack in that he still hits balls out of the zone fairly well and doesn't miss in the zone. Add to that he's very likely to stick in CF and is a lefty bat and he seems to clearly be the better value in spite of playing in a small program.
Ty Head is the one that really shocked me. He is pretty elite across the board in swing decisions, contact rates and walk rates. His power is so-so but he does a decent job of pulling the ball and given his size (6-3, 205) you may be able to squeeze a little more out of him. He also has a decent chance of sticking in CF.
Last is Ferraro. He's definitely the worst defensive player of the bunch (probably goes to 1B) but highlights that you can get an elite bat even in the 4th. His teammate Hughes gets more praise but Ferraro is a much better value with the highest xWOBA of all these hitters.
I'd be perfectly content to load up on HS guys and pitchers in the first and second then go after guys like Head and Ferraro in the 3rd and 4th.
