Yes it's absurd that the guy who spent 20 plus years being a draw and loyal company man would let Punk, the guy who leveraged his contract to force his way up the card and into the title spotlight, over Cena who has been on the grind for the company since day one and loves wwe much more and is more likely to stick around the length of time that he, Trips, HBk, Kane, and the like have thus making the loss worth something than trusting a flake. Hell its absurd to think Kane wouldn't get a third try and he be ok with him retiring him like he retired michaels and michaels, flair long before Punk ended it
But if Taker feels this way, he wouldn't have agreed to the program in the first place... This match was in the works long before Shaemus and Orton had plans for WM, so since he has enough respect for Punk to work the match then who's to say it doesn't extend further...
