It makes a lot of sense..with a wide open N.L. and the reigning Cy Young winner and MVP on their team, they are a few pieces from taking the N.L. again. D-Train plus Carpenter in the playoffs, especially a 5 game series is scary. Also with the questions about mulder and the total destruction of Marquis and the averageness of Suppan that pitching rotation could use a huge shot in the arm. Plus look at Reyes, besides one above average start he has looked nothing like some of the young rookie hurlers to emerge this year (Liriano, Weaver, Zumaya, Verlander, J. Johnson, etc.)
If I were jocketty I'd do this in a heartbeat, Reyes might be good, i doubt great, and prospects dont always pan out, with Dontrelle you KNOW youre getting a stud.
