I actually did some research, there are alot of 1st round picks in the last 10years whose names mean nothing to me.
2003 draft:
1st Round of the 2003 MLB June Amateur Draft - Baseball-Reference.com
And here are a selection of first picks overall:
Matt Bush:

Luke Hochevar:

Delmon Young:

Basicly, I don't think it's fair to expect a Bryce Harper or Stephen Strasberg every year.
