I feel bad this was glossed over. Discipline can be taught, but it's my opinion that it needs to be stressed early on in their minor league career. Granted, I think Von Joshua could get me to OBP 350 in Iowa, but that's the exception not the rule. When you have a guy whose able to get by on his raw ability through the lower levels, it's that much harder when he has to adjust to better pitching at the higher levels and come up with a completely new approach than the one that's worked his whole life. Partially pride, but you've also got the difficulty of trying to learn something new after being so familiar with an approach your entire athletic life. It's similar to why I don't like pitching mechanics being tinkered with at the big league level until forced to by injury/upcoming injury. Baseball is a game of repetition, and going ahead and changing things after you've been successful with another way is going to be difficult for anyone, let alone somebody who's been told their whole life how good they are at something. By all means, tinker with the guy when he's drafted, set him on the right path and re-teach him the game if you really need to. But yeah, this was a bit of a tangent wasn't it. As for Montanez/Colvin it's a tough comparison. Montanez struggled his first few years in the minors offensively and defensively. It wasn't really til he shifted to the OF that he started hitting. Because of this(despite coming out from high school) Montanez was ~2 years older than Colvin at the same level. The problem with Montanez was because he was so late to develop in the minors, he was pretty much sink or swim at Iowa in his 6th(and final before free agency) year in the Cubs system. After tearing up AA for 160 PAs, he was sent to Iowa and failed miserably. Totally defensible for the Cubs to let him go, as he still wasn't very projectable at that point. Even last year with Baltimore's AAA squad he didn't do much of anything. It was Montanez's 8th minor league season before he hit AAA pitching with any authority. Next year will be Colvin's 4th minor league season and hopefully he'll be up in AAA taking his hacks. I don't expect much better than Montanez's 2007 (~750 OPS), but doing that at 23 in AAA isn't awful. I think Colvin's definitely a 2 year AAAer, and hopefully that time spent with St. Von will turn him into a big league starter.
