I brought up this point in another thread concerning Larson. Second base requires an entirely different skill set than third. Second requires footwork and range, while third is more about fast hands and a strong arm. I actually think that Boone has more of the skill set for 2B. I think he will be a better second baseman than third baseman.
BTW, who comes up with this crap:
Aaron Boone's primary challenge in his new role will be learning the double-play pivot -- the subtlety that separates elite second basemen from ordinary ones, the element that makes second base the game's most difficult position to play, in the minds of many experts.
Any "expert" who considers 2B the most difficult position to play has never played a game of baseball in their life.
