I'll agree that the game isn't played the same, but I'm okay with the C not getting into a long rundown to end the inning.
Not running hard to first or admiring a deep fly ball, I also agree should not happen and should not be allowed to continue to happen. It happens so rarely however that guys that run hard every play are pointed out as being different, i.e. he hustles every play, he plays hard, he doesn't take a play off, etc...
