for the immediate future (1-3 years as you pointed out) I am taking the rios/zimm side without question. Zimmerman could be in for a huge breakout year, which is saying a lot from me because he's already considered a top 20 player with a 30/100 season under his belt, but I think he can do better and will do better this season as long as he stays healthy. I am not big on Rios, but I think he is a solid 20/20 guy for the few years with solid counting stats and a good avg. J-up/pedro def. has the potential for more upside, but I do not think pedro is going to breakout this year, I still think he has a lot to work on. I could see him being 2-3 years away from being a solid fantasy asset. J-up is a toss up, he's already had a solid year and we know there is potential for more, but he hasn't shown it yet. There is 30 HR in his bat but I'm not sure he gets there yet, I think he lost a lot of protection this offseason with reynolds and laroche gone.
so again, my pick would be the rios/zimm side for sure.
thanks for the help with mine.
