I would say Marnus did the opposite while Head was doing his stuff. Marnus kept his head and performed the unselfish team role holding up one end rather than letting his ego get in the way like all the Pommie batsmen did trying to be a hero.
Marnus went at better than a run a ball
Let’s be honest , it wasn’t Rahul Dravid crossed with VVS Laxman style holding up an end lol
Marnus came in when Head was on 50. When Head reached his ton off 69 balls, Marnus was 20 off 29 balls including just 2 fours. Not slow by Dravid and Laxman standards

but he was hardly going the whack either. He would've had the best seat in the house watching "Travball"

. It was only with only 50-something runs to win and with the Pommie bowlers shell-shocked, did Marnus start opening up the shoulders. It was a measured innings.
