Freddy Sanchez vs. Robinson Cano

vs.
Ok, switching gears. I have an internal debate I have been letting float around my head for a few days now and I can't make a decision. Someone in my mixed league just let go of
Freddy Sanchez 2b/3b/Ss Pirates
last weekend. The only guy I feel I can afford to drop is
Robinson Cano 2b Yankees
Pros to making the switch
1. and its a big one: Triple Position Elgibility
This is especially a big deal because he is elgible at two positions where I currently have no backup. Furthermore, if I made this switch, it would mean I have a backup at every position!
2. everyday moves
Though it's really an extension of pro number one, it's important to note that there will be several instances this season in which either my shortstop or third baseman gets an off day and Sanchez does not. Thing is, he probably could only help me in RBI's, as he only had 6 HR's last year. He might even be hurting me in BA and OPS (yes you're right we should only have OPS, not BA) on the days I do put him in. I think he will have more RBIs this year though because the Pirates lineup is improved. But there's no way he hits 340 again. Also I might start Sanchez whenever he plays in Colorado, though these instances will probably be few and far between (I'm not going to look it up right now).
Cons to making the switch
1. Cano's power potential
Robinson has potential to be a big star. He did hit 340 something last year, and still hits behind A-Rod, Jeter, and several other good hitters.
2. Age
Cano is 24, Sanchez is 29. Most indications are that Sanchez would be a better chance not to repeat last years success. Cano is more likely to improve, though I don't think he will hit 340 again either.
