Normally I'd start with the PR comments, since this can be improved the quickest (a month or so) with strong coaching, and will give your team better velocity.

But since your team consists solely of a maverick and a copy-paster, you're in trouble. Normally you'd fire the copy-paster and mentor the maverick (or fire him too if his ego is too big to handle).

Getting into a situation where you have to be the one to approve all PRs is a bad sign, because it shows that you have no trust in the team members. Regardless of the validity of your reasons, this is not good because you become a bottleneck.

Another option would be to look elsewhere.
