I don't know what to hope for here. If Goins continues to impress I just hope he's for real and can sustain above average defense and league average batting next year. That would make him an acceptable starting 2B next year. The problem is if he impresses the FO with unsustainable hitting and they don't bother trying to upgrade this off season even though maybe they should.
Izturis should stay on the team no matter what, but preferably on the bench as utility. He would still get plenty of playing time due to injury-prone starters in Lawrie and ReyesI like him due to his reasonable ability to play 2B, SS and 3B, something that Bonifacio certainly couldn't do, and neither can Kawasaki realistically (his arm is too weak for 3B especially). For his career (this year is an outlier), his splits vs LHP and RHP show no difference so I don't think "platooning" with Goins makes sense.
Given that we aren't getting Matt Carpenter, Dustin Pedroia, or Robinson Cano, there's no top notch 2B we can snag. Going with 2 of Goins, Kawasaki and Izturis might be the best we can hope for. (Heck, we won a World Series with Manny Lee at SS)
I've said it so many times I'm tired of typing it, the best money is probably spent on a SP to shore up the rotation and catcher.
