Barnes was not so focused on the game as he was chatting with his team and the players and cracking joke after joke. Let me give you an example.
Lineout 5m out from the Quins line. TT is down, on the 22m line and out of the way, receiving treatment. Barnes takes time off. Sinckler complains that TT is not really needed, so can't we just get on?
Barnes quips, Tommy is the hooker and needed for the lineout, unlike you Kyle, at that last scrum.
Or, half way through the first half. Barnes says, 20 minutes in and I have already had more fun than the whole of last week's game.
It just went on most of the match.
