Dexter Fowler and Tyler Colvin

I have a couple scouting reports using video analysis on Dexter Fowler and Tyler Colvin.  Both players have gone in completely different directions as players this year.  Both were similarly rated coming into this season, but both had questionable numbers and one has broken out (Fowler) and the other has not (Colvin):

Dexter Fowler vs. Tyler Colvin

My thoughts on Fowler:

Already a great defensive player, and already possessing great plate discipline, his power was really the only question mark and that seems to have been answered this year.  I had video on Fowler from last year, but I am still trying to find video on him from this year because his swing from last year (especially from the right side) were not conducive to hitting for power.

Thoughts on Colvin

I've never understood the hype Colvin has gotten.  He is a good athlete, shows moderate power, and can play an average CF.  However, his plate discipline is awful.  Not many players succeed at the major league level with a 10:1 K:BB ratio.  I'm also not crazy about his swing.

If there is somebody that was really high on Colvin heading into the year, I would love to hear the reasons because I just don't see it...
