I think I would stick with this. I am going to assume that all or most teams keep a guy in the 1st round which. So if you don't take a guy in the 2nd round, you will have a top 4 or so pick. I think I would gamble that there is either something better or as a fall back take Reyes or Verlander. I don't love keeping either guy for a 2nd round pick and I would really hope something very nice is available.
Of course you should start looking at teams and see if you can figure out what teams will have a 1st round pick and what players might be available to you in the 2nd round. If it doesn't look that good, then I would keep Reyes and hope he can stay healthy.
Agreed with this post but I would consider keeping Ike Davis, too... He had 20 second half HR's last year and he's still pretty young.
