3 A lighter schedule and a more relaxed backstage atmosphere
At present, AEW only runs one weekly television show - meaning that its roster works a far lesser schedule than their WWE counterparts. At 37, with a history of injuries, Cain Velasquez is better suited to the kind of limited workload that AEW offers.
Cain Velasquez also needs time to develop his skills as a professional wrestler, having trained seriously for less than a year. WWE needed a marquee match for last year's Crown Jewel event and so pushed their new signing straight into the program with Lesnar. AEW does not face that sort of pressure - and so can provide Cain Velasquez the time he needs to work on his craft.
As a California resident, Cain Velasquez lives close to some of AEW's more experienced talent, such as the Young Bucks and SCU, who could potentially assist in his development while he remains close to home.
Sportskeeda's own Tom Colohue revealed last week that part of the reason behind Velasquez's WWE release was that he made several backstage missteps during his time with the company. WWE officials reportedly believed that Cain Velasquez had failed to disclose a knee injury before signing his contract - and were also upset that he publicly discussed a planned surprise return in this year's Royal Rumble match.
AEW has been praised frequently by their performers for having a far more relaxed locker room environment than WWE, so Velasquez would seem less likely to face the same political pressures he did in WWE. He will have learned plenty about how best to conduct himself during his WWE run as well.
