I think if Castro was used this year like Colvin was used, he'd look like a failure too. I'm not counting on Colvin amounting to anything, but Cub treatment is an equal culprit to his level of talent. JMO.
But if how he was used this spring helps you fulfill your prophecy, fine.
I don't know how else Tyler Colvin could have been used, Curt.
He only plays four positions (LF, CF, RF, 1B) and three of those spots (LF, CF, RF) were at least to some degree productive for the first month.
The manager didn't seem to like Colvin's (or anyone's) defense in center field over Marlon Byrd.
Colvin doesn't have a ton of experience at first but he did play there against righties when Carlos Pena tweaked his wrist/thumb/whatever early but Colvin didn't hit.
When Fukudome strained his hamstring, Colvin played and didn't produce.
Alfonso Soriano hit a bunch of homers early so Colvin wasn't going to get much playing time in left as long as Soriano was the only Cub hitting for power.
Once the calendar flipped to May, Carlos Pena has been the Cubs only slugger, so Colvin wasn't going to get much time at first base.
Things just didn't break the right way for Colvin to get a lot of time in the lineup and when he did get some time, he didn't play well enough to earn more.
It made sense to send him down to get every day ABs and hopefully he can get something going in Iowa. His confidence probably needs some repairing.
I think he'll get himself straightened out and turn things around but it's probably going to take a while because, as someone pointed out earlier, he's never played AAA ball before.
I'd like to see him finish the year in AAA and put up some solid numbers... and then get traded because I don't see him as an every day regular in the Majors for the Cubs but that doesn't mean he can't carve out a nice career as a fourth or fifth outfielder somewhere else.
