Baseball Prospectus prospect pundit mock draft

Last week, I was invited to participate in a mock minor league dynasty draft sponsored by Baseball Prospectus. The rules were as follows:

The premise is very simple, we're drafting a minor-league roster for a brand new dynasty league team (no one has a major league roster yet). The "league" is a standard 15-team 5x5 rotisserie where you keep all players indefinitely with no contracts/salaries involved. The first rule is that any player you select must currently still have their prospect status in tact. The second rule is that there are no other rules. You don't have to fill any position requirements, it's just about building the type of farm system you would want to start from scratch with.

The contestants were (in draft order): Jim Callis of MLB.com, Nick Shlain of BP, Al Melchior of CBS, Craig Glasser of BSports, myself, Brent Hershey of Baseball HQ, James Anderson of Rotowire, Bret Sayre of BP, Chris Crawford of ESPN, Eno Sarris of Fangraphs, Mike Rosenbaum of Bleacher Report, D.J. Short of Rotoworld, Craig Goldstein of BP, and Ray Guilfoyle of Faketeams.com/SB Nation.

There were 10 rounds in all. The articles are NOT behind the Baseball Prospectus paywall, so go take a look.

Rounds One and Two
Rounds Three and Four

There is an owner commentary for each choice.

Through round four my system consists of Corey Seager, Franklin Barreto, Kyle Schwarber, and Luis Severino. What do you think of those choices, building a farm system from scratch?
