I think as salaries increase, drafting and development are going to become even more important. If you need 45 WAR to be a playoff team (45 wins is roughly what a team of replacement level players would do), and the free agency cost of a win is $5 million, you can maybe try to be the Yankees and spend $225 million to get your wins entirely in free agency. If wins cost $7 million in free agency as they did this offseason, you're at $315 million to build the same team, and that's only a team on the EDGE of the playoffs, not a sure thing.
In my perfect world, I would just pay overmarket prices to sign our young players to extensions that end by age 32-33. I'd rather just give a bunch of guys $100 million for their primes than face this choice of paying them $30 million in arbitration but losing them unless you pay them another $140 million for their decline years.
