Back to the topic at hand, the 07 draft looks to be a bit more top-heavy than the 06 draft and "should" have a deeper overall talent pool.
At the top, guys like David Price and Matt Wieters lead the pack of college players. Both players are legit candidates for 1:1, but I think Price should be the top player off the board if he can have a strong junior season as expected.
Wieters swings a big bat and should be a no-brainer for the top 5, but there are questions about whether he can stay at catcher. He is 6'6" and if he stayed at catcher he would arguably be the biggest catcher in MLB history. However, if he made the move to 1st he would still be a top pick purely based on his bat.
In addition to the college players, the high school prep market is much better on paper than the 06 draft. Elite talents like Michael Main and Robert Stock look to be top 10 picks next year, but so much can change with one good or bad senior season (see Clayton Kershaw).
