There's a huge difference between the 2. Chris Jericho traveled around the world learning his craft. By the time he took his first "leave of absense" he has been in the business for 15 years! He was also at a low point in his career in WWE and as stated in his book UNDISPUTED was getting a rep for just being a "good hand" instead of a main eventer. The 2 years he took off gave him time to recharge his batteries, spend time with his young children, and come back to us better than ever. Also, whenever Jericho make an appearence on anything, he's still Chris Jericho, not Chirs Irvine unlike Dwayne. Now after 4 years he's doing it again. He'll be back, and be awesome. He never really leaves. Look at Triple H, Shawn Michaels, and Undertaker. They work wrestlemania and then take half the year off as well, so its not that much different from Jericho, other than Jericho wants total freedom from a contract.
The Rock is a completely different story. He worked from 96' to Summerslam 2002 (not even 7 years) when he dropped his last WWE Championship to Brock Lesnar. That was the last time Rock worked a full time schedule and even then was taking time off for Scorpion King. Sure he came back for X8 to wrestle Hogan, then again 19 for Austin and brief feud with Goldberg. Around long enough for a cup of coffee with Mick foley a couple years later. He stopped going by THE ROCK and became Dwayne Johnson, and didn't bother to do another live appearence for 7 long years. He'll never wrestle let alone a full time schedule again unlike Chris Jericho. Rock's wrestling wasn't half as long as Jericho's and Rockys been out of Wrestling as long as he was in it at this point.
I'm still a Rock fan, but the difference with Jericho is world apart
