The general philosophy of not spending big money on a free agent is a good one. dont pay ridiculous prices for the down years of production when you can often get similar production from younger, cheaper players. that's been a mantra from the more analytical type observers for a long, long time (shoutout to baseball think factory and those of us who used to read rany and rob on the royals...).
however, there are exceptions to that rule. i would argue that the tigers were in such an exception when they were blessed with one of the best pitching talents of his generation and seemingly decided to only tinker on the margins to help them win.
results wise in the major leagues, i think its hard to argue harris has improved the major league team dramatically outside of skubal's starts. when skubal doesnt pitch, the tigers are decidedly average.
results wise in the minor leagues, the tigers have succeeded in producing some highly anticipated talents. if they pan out, harris' approach may yet be vindicated. my analytical brain likes to think it will be. my "old man who has watched baseball for 50 years" side still has doubts.
