That's basically it. They don't need a payroll increase to improve the team, they need it to improve the organization. That comes with signing Cuban/Japanese FA's, or improving the farm system, or having available cash to add talent when necessary during the season, etc. Increasing payroll so they can afford Bautista, or whatever narrative the casual fans want to go with, won't accomplish anything positive for the org.
The Jays have smart people working in their front office. They can win with the payroll where it is now. If Rogers increases it, then great, but I don't think it's a prerequisite.
