Anybody who is not Thompson, Tuch, skinner, cozens, dahlin, samuelson, or power are slots that need to be improved upon.
Not saying all those spots need replaced. Some slots will organically improve. Some are fine in their role but not expecting anything more. Don't want change for the sake of change but retooling the slots mitts, Olofsson, or joker occupy would be a plan. Revamping the bottom 6 or bottom pair would be a plan. Don't need to do everything at once but maybe at least pick 1 or 2 spots and just try something different. Bringing everyone back next season and expecting different results is......
