Everywhere he has gone as offensive coordinator his offense has averaged better results per S&P metrics than Orlando's defenses have when he was defensive coordinator. Now, you might can attribute it to Beck having more talent than some places than Orlando did or small sample size, but you can't deny that Orlando has been poor some, too. However, he gets the free pass. Why? Because of the part of your sentence "last year." Orlando's results say he may throw out a stinker, but you feel that he is on an upward trajectory because his most recent results have been good.
Maybe, just maybe, Todd Orlando is getting better at his job the longer he does it. This is year 17 for him as a defensive coordinator. Maybe he is continuing to learn and grow. Maybe Beck in his 8th year as OC will start to have similar luck. Maybe he won't. We were all pretty damn sure that Manny _iaz was a fool just a few short years ago. The guy wondering if we can hold onto Orlando for five more years might be wanting to seem him fired after game 1 next year.
To sum up, I don't think anyone on this staff deserves kudos or a firing based on what they did last year.
