Is Unclutch a word?

[Chukarhawk]

Because this team is decidedly unclutch. Pete Carrol teams usually get better as the season goes on, but this overachiever looks like the wheels are coming off. That was a waste of my time today. The team I watched today loses the rest of their games in a similar fashion. I need go back to being a naysayer, they played a lot better.

We're looking for "What is Choke", Alex.

The antonym for clutch would be choke.
