The best and worst defensive centres in the NRL ?
That seems a very convoluted and arbitrary appraisal to say the least. I wouldn't be surprised if the list wasn't thrown together at the wrong end of heavy session at the pub.
Chambers is at No 1 on that list but he's 6th in missed tackles for Centres, 3rd in penalties conceded and just out of the top 10, at 11 for errors. He also plays in a very well drilled defensive side.
Only 3 of the top 10 on the list played close to a full season in the position. Mann only played 7. I wouldn't read too much into it.
If Mann gets a centre spot it will be for his speed, evasiveness and pure skill I reckon rather than defence.
Having him on the right with Hunt and Nene seems like a good idea to me, more deadly in attack than Hunt / Aitken / Nene combo. Mann is a scarier option for the defence than Aitken as they're less likely to rush up on a guy who can step, kick and pass. Aitken can step and run hard for sure but largely predictable ( unless you play for Manly ).
Put Widdop, Lafai and Field / other fast young guy on the left and we'll do alright.
