Those situations were completely different.
Taillon was frequently injured and eligible for arbitration for the second time, and was getting more and more expensive, and had missed all of 2020 with his second TJ surgery. And was only controlled for 2 years. Reynolds shows up for work every day and still makes minimum wage for another year, and is not eligible for free agency for 4 more years.
If the Yankees want Reynolds, the price will definitely include at least one player you don't want to give up...
