While it is possible Nolasco COULD be for twice as many years, it should be noted that he is looking for 4 and Arroyo is looking for 3. There is nothing that says Nolasco can't be brought in for 3 years. Also, he is a much better better pitcher then Arroyo. His FIP and xFIP are significantly better than Arroyo over the past 4-5 years. Arroyo had a total WAR of 5.0 over the last 5 years while Nolasco has a 13 WAR over the past 5 years and had better season over season WAR then Arroyo in 4 of the 5 years. Additionally, Nolasco is 7 years younger than Arroyo, and at age 37 Arroyo is a very good candidate for significant regression (this coming off a season where his WAR was a paltry 0.8) Nolasco is still in his prime at age 30 and coming off 3.1, 2.5 and 3.0 WAR years the last 3. Also, Nolasco also strikes out a decent number of batters, and the Twins DESPERATELY need someone like that on the staff, Arroyo is nothing more than a slightly better version of Correia. So yeah, Noalsco would cost more money, but that is because he is a significantly better pitcher.
