It will be Stephen Strasburg if it is based on talent. He is dominating at San Diego State this spring. He is 3-0 with a 1.77 ERA so far with 45 k's and 4 BB's in just 20 1/3 IP. He has reportedly hit 102 mph on the radar gun this spring. For all these reasons, he should be the first overall pick in the draft. Recently Jim Callis at Baseball America has stated he wouldn't trade this pick, if it was possible, for a package of prospects only for the likes of Justin Upton, Evan Longoria or others.
I, on the other hand, would trade him if it were possible. Even if I owned the 1st overall pick, I may not take him. He does have superstar potential and could be in the major league rotation as soon as 2010. He could follow the likes of David Price and make an impact very early on. Personally, I am more afraid he will take the path of Mark Prior or Ben McDonald.
I look back to the 2001 draft when the Twins took Joe Mauer over Mark Prior. Dewon Brazelton and Gavin Floyd also went before before Mark Teixeira. I think the Nationals should look at this and take the safer route and go with Green or Ackley.
