I went and compiled the full ratings list:

So the show was definitely trending upward, but I'm impressed it managed to pick up almost 700,000 viewers over its run. I'm not sure it was just because Leon was let go, but I'd sure like to believe it was.

It's more likely people either really liked Rocky as a character or the Rocky/Eddie storyline, or they simply just remembered the show was on, but Leon's dismissal definitely didn't hurt things. People weren't sticking around for him, despite what he'd like to believe. (For what it's worth, I think Ben's a better character, anyway.)
