Jim Bowden has an article up where he predicts final contracts for each FA. Relevant to the Reds:
Michael Bourn 5 years, $75MM
BJ Upton 5 years, $70MM
Nick Swisher 3 years, $33MM
Torii Hunter 2 years, $20MM
Kevin Youkilis, 2 years $18MM
Ryan Ludwick, 2 years $13MM
Jonathan Broxton 2 years, $13MM
Ryan Madson 1 year, $7.5MM
Hypothetically, if the Reds could pay $15-$17MM on FA, who would you want?
I'd take one of Hunter/Ludwick/Youkilis - probably in that order, and Madson.
No thanks to Broxton at 2/$13M and a BIG no thanks to Bourn or Upton at those prices.
If the Reds are confident in Marshall or some other in-house option closing, or they want to keep Chapman in that role, I would also consider Swisher at 3 years and $33MM. He could play CF against RHP and LF against LHP, and move to LF permanently once Hamilton is ready. He is also a semi-local guy (WV native and OSU alumni).
