Some interesting choices so far...
Dye is a very good one. I can't imagine he will be a top 15 player again. Should hit for 30+ HRs but I expect a big dropoff as well.
I think Atkins will disappoint also but not to Beltre's level.
I am going to throw Hanley Ramirez out there. I think he is a great talent but will see a noticeable dropoff in production.
