Katz vs Mannion

I didn't think this would even come up to be honest. Not at this point in the season.

It looks like Katz is a liability. Mannion is upside. 

Agree or disagree?

(Update- Riley has admitted to a closer competition between Mannion and Katz, but didn't want to go public and start a QB controversy. Which is possibly the stupidest thing I've ever heard of for dozens of reasons.)
