I think Hicks will be fine, if healthy all year.
Last year, Higgy had over half the PAs as Sanchez as a catcher (209 to 409), so you had some weakness at the bottom, last year, too.
The SS drop off on offense will be plentiful, but the gains on defense he brings at SS, plus the gains you make at 2B and 1B, because of him should be worth it.
