Those are not stats, they are "what if...".
Well said. What if Clem was left in (as Carp has more than him)? Would his ERA escalate?
To extend this, 'what if' Carp were removed from each game where he pitched the 'leagal # of innings' and had no runs scored? Wouldn't his ERA go down? Would it help the team or just elevate his personal stats?
