Holy crap would my load blow through the roof if John Morrison was added to the TLC match between Punk & Hardy.
I'm sorry, I might be the only person who wants to see the TLC match, but at the same time hopes it gets something more added to it, since we've seen a similar style (ladder) match already, within the past 3 months. At least. And Hardy was involved in that one, just the same, as well.
Punk and Hardy haven't had "great" chemistry together, and Morrison may very well be the missing piece to the puzzle. Regardless, as much of a Morrison fan as I am.. Justin was correct. He is not ready for Main Event matches just yet. Don't just throw him instantly into something, before he's ready, otherwise you'll get a shit-fest and a failed future star.
Morrison has all the in-ring ability he needs. Working on selling might not hurt, but his promos as Justin also mentioned, are his weakest point. Which is confusing to say the least, considering he has one of the more "wide open" characters, you'd think his promo skills should be better than sub-par crap.
In the end though, adding him to the TLC match may not be shoving him, so much as testing the waters for him. Hell, Hardy tested the Main Event waters for a few years (2001, 2002) before he was finally given the green light to run with it. So you never know.
