Sidious, here's the problem with Cena being the one to end Taker's streak - he's already on a quasi-fine line with many of the fans. If Cena defeats Taker and ends the streak, there is a percentage of fans who will absolutely turn on him and mercilessly boo him. So unless there are plans to turn the clean-cut good guy and merchandise cash cow in Cena into a heel, it's a poor option every way you look at it.
I think this is a little over-exaggerating what would likely happen. There is a fine line with wrestling fans as it pertains to Cena. Either you like him or you hate him. At this stage of the game, he is a very polarizing figure, and that line has been drawn with fans the moment they start watching WWE and see him.
In other words, you aren't going to like Cena today, and then turn around and hate him after the match for ending Taker's streak. Hell, there's a lot of people that don't care for Undertaker anymore either, because of his frequent coming and going. They probably would be happy if Taker had his streak ended by anyone, even Cena.
Although, I agree, it would be a big move towards turning him Heel. But that is all in how they book the match, and whether they make Cena look heelish in doing so.
But they obviously aren't going to give this win to someone really young, as they don't deserve it. Quite frankly, it's entertainment. I see no harm in giving the win to a veteran, in the name of entertainment. However, the key is to make it at least someone who has a couple years left.
Michaels, on the other hand, arguably came the closest. I went into Wrestlemania last year knowing in my heart that Taker would win the match. Shawn Michaels, in his infinite selling and storytelling ability, actually made me question that at several times last year.
I was fairly certain Taker was winning the match as well, from the get-go. However, I wouldn't have even objected if they gave the victory to Michaels ... again in the name of Entertainment.
As a Booker, I wouldn't necessarily be as concerned with using the streak to give a rub to someone, as much as I would be to continue to use it as a selling point and intrigue factor for Mania. There are an infinite number of ways to get talent over with the fans. And if the only way they can think of to get someone over is to give them a win over Taker at Mania, then I pity them. Quite frankly, maybe Creative should look to members of the IWC if they continue to struggle in this category. Either that, or look to their CEO and Head Writer, who is actually holding them back.
If Michaels decides to put his career on the line against Taker's streak, then I give it 50/50. It's just as viable that Shawn would parlay a win into a last World Title run as it is that Shawn would lose and call it a career. It's also possible that Shawn could win and put 'Taker over by stating that no possible moment in his career could be bigger than this one, and walk away gracefully.
And I would agree. Although I don't necessarily see the benefit to Shawn in doing a Career vs Streak Match. A streak is not on the same caliber as a man's career, in my view. You figure "Big deal", I ended a man's streak so he couldn't end my career. Now, what else do I get out of it, other than saving my career? How is Taker negatively affected since MY career was actually at stake, and he still can continue his?"
Now, if it were a Career vs Career match, then that really would spice things up.
Chris Jericho is the only other guy I can think of right now who 1) has a realistic shot to beat Undertaker and 2) would benefit from it at his age and point in his career.
Give Jericho a new character other than this completely over-rated generic one ... along with a renewed push .... and give his age, I would be inclined to agree with you.
