Fangraphs notes that Bill Hall is most likely going to become a free agent this winter. What if we put him at 3B, moved Pedro to 1B, and left Walker to get better at 2B?

No one loves the FA upgrade options at RF or 1B, and Orlando Hudson seems to be the only decent upgrade at 2B, and he might be pricey. Furthermore, there's a better than even chance that Rendon gets drafted and becomes our 3B by mid-2013, which makes you wonder if it's worth jerking Walker around the infield in order to win a couple more games in 2011 and 2012.

Hall is a career 3.9 UZR/150 at 3B; his career wOBA of .322 is middle of the pack for the hot corner. He is about to turn 31, so he could turn into a pumpkin, but the odds are probably for more of a modest decline. Hudson's got a better career wOBA (and better over the past 2-3 years), but he's about to be 33 - I don't think you can fairly project a big decline for one but not the other. Hudson's career UZR/150 is actually just 2.2 - he's been extremely variable - so, depending what you think Walker can accomplish with a full offseason/ST at 2B vs. moving back to 3B, it's not clear that there's a big defensive tradeoff either way.

I don't have a strong opinion, but it's an interesting idea to ponder. Do you want Hall or Hudson, and what would you pay for either?
