How to Screw Up an Easy Rack of 9-Ball

In this video I get a decent break, dropping 3 and leaving a very manageable table. Only issue I really saw off the break was setting up for the 7, 8, and 9. I managed to get precisely where I wanted to be for the 7 to set it up, but then rattled the pocket.

Perhaps it was a letdown in focus after executing to get exactly where I wanted for the 7. I'm also sure I could have approached it with a different plan for the 7, 8, and 9. Either way I screwed up a gimme rack.
