Management should absolutely focus on problems. Managers should then work together to propose solutions. Once a solution is agreed upon, communication with the team should only be about the solutions. The players should, then, only be hearing about how to improve (the "solutions.") One can't pick one or the other when it comes to problems v. solutions, but every person has a different role in the workflow. Note that every worker/player is different. Some people respond well to having problems called out so they know exactly what they are trying to fix. Molitor's job is to figure out which approach works. For most of the young guys, the solution approach is probably better. It's certainly what should be tried first.
