"I don't think that means what you think that means" [/Inigo Montoya]
The Raiders were not in a kneel formation. They were running a play out of shotgun before the timeout. After the timeout they ran a play from under center. The change in strategy was they changed their play call, not whether they were going to go for a tie.
If we want to say since the play they changed to succeeded and got in better FG range, it was a failed timeout. But we don't know the play they were in first wasn't going to go for even more yards. We can only speculate.
Yeah, worrying about the timeout is overblown. Didn't impact the game in a way we can say for sure.
