And that's not the point. The Reds need to pay money to pitchers who can elevate the staff. Wilson, at his best, only manages to keep the team from constantly scraping bottom. The Reds just spent $3.6M on what they don't need. I have no issue with them spending more to get what they do need. I'm all for them spending more to get what they do need.
The point is that the Reds paid market value for Wilson, maybe a little less.
The next point is that of the NL FA pitchers with Win Shares equal to or greater than Wilson will all be significantly more costly than him, and quite possibly for not a lot of added production. Folks salivate over Matt Clement and his three additional Win Shares. Why is Clement worth $5M (or more) a season more than Wilson for three extra WS?
