I can't speak for other people, but the main reason I care about players' salaries is that the team only has so much money to spend. We can argue about self-imposed caps by the Twins all day long, but when it comes down to it, they only spend so much on the players. It's all about value. A team built around players earning less than they're "worth" should have money to go out and get that slugger on the free agent market. They can go get that SP that puts them over the edge. I want to have a team that's being paid $100M but WAR says should be paid $200M or $300M based on production. This year has basically been punted on, but rebuilding should mean shedding contracts that overpay (think Vernon Wells and Soriano) based on past production. Which is good for the long-term health of the organization. Then you build your nucleus by locking down consistent players for under market value, leading to an excess of money to fill out the roster with whatever you couldn't develop on the farm. Basically I care about players' salaries because i think that getting better value out of current contracts leads to more wins and the potential to fill holes. Sorry this was so basic and maybe even patronizing. I just think it's something that should be cared about and understood for everyone hoping for their team to get W's.
