Going 1-year with Jack Wilson may be the most realistic solution here if Scutaro prices himself out of range... I wouldn't mind a $1mil flier on Khalil Greene either (high risk, high reward).
Adam Everett might be your stop-loss plan if J.Wilson is asking for too many $.
Personally wouldn't mind a Greene+Everett job share at SS either if your looking to save $. If Greene's bat comes alive he takes the job, if not hes the back-up to Everett.
