All those are pretty consistent. Just your normal variation from year to year.
Now if you want to say Mac has declined from when he first came up. Sure you can say that. He had a higher average then thanks to a much lower K rate and a high BABIP a couple of years. But right now? No he's not in decline. He's pretty much been the same hitter for the last 5 years.
The reason for McCann's drop in BABIP is because teams started playing that dead shift against him and he has never adjusted to it. When McCann first came up he used the whole field as a hitter. But then he became a dead pull hitter for the most part so once teams made the adjustment defensively to account for that McCann's average and BABIP dropped like a rock.
