I watched Alex Meyer's last few starts, and I think he's a steal at 23. He was throwing mid-to-high 90s with a nasty, late breaking slider. He was repeating his delivery well and not walking many, despite what I thought was a very tight strike zone.
What is scary is he only really started working out last year. He could still add a lot of weight to his thin frame. So you could be looking at even greater velocity. Also, this is a guy who is 6'9", so it feels like he's right in front of you when he releases that ball, thus making the fastball seem even faster.
I've seen video of Goodwin. He has impressive tools. His arm was what surprised me the most. He can really run as well. I'm not a scout, but he reminds me of Ellsbury in terms of tools. Not as fast, but more power potential IMO ( More than your typical Ellsbury, not counting this season).
We'll see if these guys sign, stay healthy and how they develop, but it could go down as one of the best drafts in history. Skole looks like a great pick. Taylor Hill looked really good in a start I saw, although he is older.
