Should i do this trade?

Yes. Reyes is an awesome talent and will post incredible numbers but Granderson isnt quite ready to be a conbsistant fantasy producer. Soriano and Rollins are proven fantasy studs and Rollins is already on top of his game and Soriano seems to be poised for the big breakout. So essentially it is a 2 for one deal and you keep a top producer at SS and add a top outfielder (which it looks like you could use). It makes you decidedly better so make the deal.
