Those issues are fine for you.... because you are a human with freedom and creativity.
Those are, however, critical issues for the CPU controlled teams. The CPU doesn't move their excess guards or tackles to center. The CPU doesn't get 75-80 rated kickers. The CPU doesn't do anything logical with their rosters outside of recruiting.
Us human players will always find a way around minor annoyances, but the goal of you guys at EA should be making sure that the CPU has the correct logic so we aren't left with an irreparably damaged product like the one we have right now.
