You were lucky , sal.
You missed Cullen's attempts as a half back, which were poor, at best.
As a centre, he reminded of Carl Gibson (Leeds centre late 80's early 90's). No idea, attacking wise, but little got passed him, defensively (Gibson, amazingly, went on to play for GB).
A total revalation, when he moved into the pack.
He almost reminded me of one of those characters from those clichéd war films. You know the ones. Always the first to go into battle, with no thought of his own safety.
(iirc) his move to the pack, was due to his loss of pace (if he had any) after knee/leg surgery . Thank God for that injury.
For that reason alone, Cullen DOES deserve the tag underrated, for his forward work
