The intentional grounding call was correct.

1. There was on offsides penalty against the Browns on the previous play that we declined.
2. This means the game clock is stopped within 2 minutes in the first half (even if the penalty is declined).
3. You can only legally spike it when the game clock is running before the play.
4. 1 second ran off because that's how long it took Mahomes to spike it.

Er - that's assuming that #3 is actually a rule.
