Here are my thoughts. Some guys are just untradeable based on what they make, Tigers would have to send a lot of money along with them. Those guys are:
Miguel Cabrera - 2016: $28 million, 2017: $28 million, 2018: $30 million, 2019: $30 million, 2020: $30 million, 2021: $30 million, 2022: $32 million, 2023: $32 million, 2024: $30 million vesting option, 2025: $30 million vesting option
Justin Verlander - 2016: $28 million, 2016: $28 million, 2017: $28 million, 2018: $28 million, 2019: $28 million, 2020: $22 million vesting option
Justin Upton - 2016: $22.125 million, 2017: $22.125 million, 2018: $22.125 million, 2019: $22.125 million, 2020: $22.125 million, 2021: $22.125 million, 2022: Free Agent
Jordan Zimmermann - 2016: $18 million, 2017: $18 million, 2018: $24 million, 2019: $25 million, 2020: $25 million, 2021: Free Agent
Guys that you could trade and would still have to send money with, but still a possibility:
Victor Martinez - 2016: $18 million, 2017: $18 million, 2018: $18 million, 2019: Free Agent
Anibal Sanchez - 2016: $16 million, 2017: $16 million, 2018: $16 million club option ($5 million buyout)
Guys that are basically dead weight:
Mike Pelfrey - 2016: $8 million, 2017: $8 million, 2018: Free Agent
Mark Lowe - 2016: $5.5 million, 2017: $5.5 million, 2018: Free Agent
Guys that could be easily traded but based on their salaries but should be kept:
Jose Iglesias - 2016: $2.1 million, 2017-18: Arb. Eligible, 2019: Free Agent
Nick Castellanos - 2016: Pre-arb. Eligible, 2017-19: Arb. Eligible, 2020: Free Agent
Others:
JD would get you a good return. But he is only under contract for 1 more year so in terms of freeing you up money doesn't make as much sense since it's only 1 more year at a bargain salary, IMO.
J.D. Martinez - 2016: $6.75 million, 2017: $11.75 million, 2018: Free Agent
Kinsler gets cheaper. He could get you a pretty good return but again this is probably a guy I keep around.
Ian Kinsler - 2016: $14 million, 2017: $11 million, 2018: $10 million option ($5 million buyout)
K-Rod....6m to keep him 2m to let him go...I definitely keep him around.
Francisco Rodriguez - 2016: $7.5 million, 2017: $6 million club option ($2 million buyout)
Maybin, I pay his 1m buyout and try to resign him for 1-2 years at 4-8m total. Then put a clause in his contract that he has to live in a bubble during the off season. No way I pay the 9m option for 100 games.
Cameron Maybin - 2016: $8 million, 2017: $9 million club option ($1 million buyout)
