I see it differently. Rick understood the product. He was not bothered about writing code properly, he wanted to get working product out of the doors.

I am writing that, because once I was maintaining code after similar Rick. In the code were lot of "dumb errors" which turned out to be undocumented edge cases and thanks to those "dumb errors" code performed much better than competitors code. So I would take with a massive grain of a salt an evaluation of a code by a person who took over the code of such Rick when this person also had antipathy towards said Rick.
