I read hundreds ( not hyperbole, hundreds ) of posts about how Kelton ( and Choi and Bobby Hill etc ) were the future of the Cubs, but I do not recall a single post proclaiming he had an untouchable immaculate swing, or anything of the sort. Colvin has already achieved far more than David Kelton, and to compare them is inaccurate at best. Colvin may well fizzle out, but at equal points in their careers Colvin shows much more promise than David Kelton, who OPS'ed .750 in his last two seasons in Iowa. In fairness to Kelton, injuries didnt help. There were lots of reports on how the Cubs loved Kelton's swing and didn't want coaches messing with it through out the minors.
