Wrestling shouldn't have an offseason but individual wrestlers should be given time off every so often to let them rest and get them ready for their next storyline.
The WWE usually doesn't try hard enough to get new wrestlers over, they are very risk averse and they worry about trying to put on a PPV without the same old faces in the main event. This year, SS is one of the gutsiest cards in years. I fully expected Bryan to win MITB and have his feud in smaller PPVs (Night of Champions, Hell in a Cell) while Summer Slam took the lazy route and had Cena vs Orton as the main event.
Props to them for that, but they've still buried Barrett, Cesaro, and Ziggler while keeping old guys like Christian, RVD, Mark Henry and Big Show higher on the card. On top of that, if they don't work the Cody Rhodes/Damien Sandow feud, one of them could end up buried as well.
