Is Heath Shaw a must have in defence this year??

[aces-high]

Atm i have Heater but im curious to know what everyone elses thoughts are on him? Will players like Birchall, carrazzo and adcock average the same and or more as him? If i get one of those three it allows me to finish off my team and get the best rooks possible. But I feel as though Shaw may go nuts this year and the thought of missing out on that is stressing me :S All opinions appreciated, cheers guys :D

Don't think he is a must have but reckon he is a solid choice

[Ricochet]

definitely not a much have.
Gods and Lids are locks but definitely not Shaw
I think his price atm is where he will stay, can't see a hell of a lot of improvement in him
