These sorts of generalizations do not end well. For example, if you really think that "There aren’t people who are A players and C players. Just people who are performing at an A level and at a C level." then fire your entire recruiting department and hire anyone who walks in through the door. After all, there are no bad people, only those who perform badly right? So if those strangers who walk in do not do well, it is the fault of your environment and management, right?
