Should I pick up David Freese?

It's certainly worth a gamble. I've never been a big fan of Polanco as a fantasy player... he gives you good AVG and decent R, but he's only hit 10 HR once in the last 6 years, he hasn't had more than 7 SB since 2003, and he doesn't give you many RBI at all. You need more than a guy who hits for AVG and gives you some R at 3B. Freese has the potential to give a solid .280-ish AVG, but he has more power potential. You won't hurt your team by dropping Polanco, and if Freese gets back to what he was doing before he got hurt you will probably get a big upgrade. There is an "if" there, but it's a pretty small one and it's not like Polanco is carrying your team right now. You can find lots of guys on the waivers who do the same thing as Polanco if it doesn't work out.
