I want to see us sign Wilson, but I think you're right about him getting overpaid. I could see the Yankees throwing some money his way, especially with what he's done against Boston this year. Any free agent is going to be a risk (see Werth, Jayson), but I think I would rather take a chance on Wilson as opposed to Fielder. His weight scares me.
Uhhh ... Cecil Fielder was fat his whole career and was fine. David Wells too. I just don't think weight is as big a deal at a corner infield position. Especially first. No one is expecting him to run the bases particularly well. Its not like Morse or Laroche are speedsters.
If they only re-sign Zimmerman? How exactly did they improve the team?
They kept Zim here for his career. That improves the team.
Honestly, does anyone really think Werth is going to repeat this season? I don't. He'll have an average around .270 next year. Danny Espinosa isn't going to hit as poorly next season, I hope. While he'll never be a .300 hitter, I think he's capable of hitting .260. Same thing with Ramos. And, hopefully, we'll be getting rid of Desmond in favor of Lombardozzi.
In other words, the offense will improve simply by the experience gained this season. We're starting two rookies full time and Werth is having a dreadful season that I don't see him repeating.
