Grady Sizemore? Tyler Colvin?

Tyler Colvin is my middle name.  No, seriously check my facebook page (for a limited time only).  My question is: How do the Cubs, notorious the last decade or so for spending the big bucks on busts and the like and investing in the wrong prospects from a dismal scouting system, end up with a prospect who leads the entire Cactus League in batting average?  I can't answer this question, but I am really glad to have a young talent on the Cubs this year.  For once, we aren't a completely veteran-laded team with a really young bullpen.  John Grabow is the only reliever at 30 or above.  Anyway, Tyler Colvin should be compared to five tool outfielders in the big leagues, and while Grady Sizemore is a stretch, it is a possibility down the road.  Colvin didn't show much power before, but he's beefed up and the Cubs have said he will get 2-3 starts a week in the outfield at any of the three positions.  I think this makes life tough for Kosuke Fukudome, because I think either Xavier Nady or Colvin is going to steal his job.  Colvin is the guy the Cubs have been searching for all these years, and we finally have NO question marks in the outfield for the first time in maybe five years.  Soriano's health is a question mark, you might say, but there is enough talent and depth that we could win without him.  Nady is a step down because he doesn't have much speed and less home runs and all that, but definitely an above average hitter still getting 20 HR.  If Tyler Colvin were to take the spot in left, well, what can I say?  Sit back and watch the guy do his thing.  You won't be disappointed.
