You look at Segura's minor league numbers. And I would do that trade again in a heartbeat.
Rookie Ball 162 AB, .904 OPS
A Ball 515 AB, .829 OPS
2011 looks like he was hurt, only 185 AB in A+ Ball .758 OPS
AA Ball, 374 AB .749 OPS
Traded to the Brewers. 148 AB, .652 OPS last year.
Then he jumps to a .986 OPS this year. If anyone could have predicted that, especially many posters, I call Bullshit.
