There's something that is concerning me.
Remember when Bula first hit the scene and everyone was praising his efforts in defense, particularly in that last ditch effort to stop a try in the corner.
I know from experiences that one of the ways to stop these attacking raids from scoring in the corner is for the whole backline to reduce the amount of time the opposition has to catch, pass and run. There are several ways you can do this but one thing you must not do is hang back. You can't run parallel to the tryline either, if your doing that, the chances are you arrived too late.
A fullback needs to reduce the gap between him and the attacker by increasing the angle in which he is running and to react quickly, sprinting in most cases.
All of a sudden Bula stopped doing this and it resulted in several tries being scored out wide.
He stopped reacting quickly and hung back.
Mason isn't a classic fullback and an example of what I'm talking about is in the vid below. At the start of the vid you'll see him meaner across field, parallel running and gifted Manly a try.
I blame this on coaching and a disconnect between the defenders.
To the contrary when himself slid across the line to score in the first half you'll notice who was there to nearly stop him from scoring, it was Turbo Tom.
