Grounded in reality? Almost every major league team has gone for a mid-range free agent signing at some point. Besides the poorest of the MLB poor, almost every team could afford 3/30-3/40 contracts. Do I need to go through all of the biggest free agent signings from teams like Miami, Seattle, Minnesota, Milwaukee, Colorado?
Last offseason Boras was trying to sell Drew as more than just a shortstop. Based on his role with the Red Sox, it seems that he wants to stick at SS, but I don't think it would be out of the question to see him at 2B.
Kansas City is in win-now mode and could use a shortstop. The Angels may go for broke and replace Aybar after a mediocre season. The Yankees could very well make Jeter a full time DH. The Pirates might want to try to win themselves a fanbase.
The other factor is that GMs all across baseball will be looking at how the Red Sox rebuilt a team from nothing to a World Series champion, and will probably try to imitate the effective strategy of hitting on mid-range signings.
