We already know the benefit of giving wrestlers consistent time off. There obviously will never be an official "off-season", but it's certainly possible to give wrestler A these two months off, wrestler B these two, etc. So from the wrestler's perspective, thinking about their health, their sanity, and saving them from getting burnt out, this really is a no brainer.

Now, considering C.R.E.A.M. and all that, ADR's return last night proves that it's beneficial from a business standpoint as well. What was ADR doing before he left? Does anybody even remember? What would he have done for the past year or so that he was gone? Continued to get more and more stale, rehashing the same feuds, fighting Sheamus, Randy Orton, etc for the million times each. Instead, he's gone for a year, comes back refreshed and without a million appearances over the last 12 months, and he's immediately 10x more interesting than when he left. ADR is worth more money from now until WM32 than he was the entire time he was gone.
