I think you nailed the core issue. The OP says the team is capable but is failing. Either they can do the work but don't want to; or the more likely scenario is that they can't do the work. The OP said most of the developers were straight out of school. If it is the former, then management will "motivate" by demanding more stringent agile processes aka more meetings. If it is the later, then management will need to admit their hiring and staffing practices are lacking which they are not likely to admit to.
