I don't think The Miz looked bad at all. When you break it down, here are the facts:
- Jerry Lawler is a Hall of Famer
- 'Old timers' can pull out suprising performances as a result of adrenaline, determination, etc...
- A TLC matchup is a match where suprises can happen due to hithe dangerous surroundings, as Punk kept saying, it only takes one mistake.
- This was the town of Rocky, where underdogs shine.
Taking all these into account, it's plausible that Jerry Lawler could have won the match. Also, in the broader picture, the match gainedeven more heat for The Miz and Michael Cole, which can't be a bad thing. The match was believable and it did its job.
