Keep in mind their salaries. Who would you rather have? Yu Darvish or Wei-Yin Chen?
Chen
2012:
- 2.2 fWAR
- 3.70 ERA
- 4.09 FIP
12:$3.072M, 13:$3.572M, 14:$4.072M, 15:$4.75M club option ($0.372M buyout)
Darvish
2012:
- 3.1 fWAR
- 4.51 ERA
- 3.74 FIP
12:$5.5M, 13:$9.5M, 14:$10M, 15:$10M, 16:$10M, 17:$11M
Keep in mind Texas paid a $51 million posting fee. That money does not go to Darvish, but it is almost as if they are paying him an extra $8.5 million per year. So:
12:$13.5M, 13:$17.5M, 14:$18M, 15:$18M, 16:$18M, 17:$19M
I'd much rather have Chen because of the value. Darvish is the better pitcher, but maybe by 1 - 1.5 WAR per year. Chen has a better contract, better value, and there is less risk.
