Ability should mean more than price tag
The primary consideration when a team acquires a player should be how good he is, not how much he costs.
All the money in baseball, I mean. There's so much money in baseball that now, quite often, when a player signs a new contract, rather than asking "How good is he?" we ask instead, "How much is he?"
That second question certainly is important. But for a contending team, it's not nearly as important as the first question.
