He is selected every week regardless of others availability, regardless of form, regardless of other players.

The picture you paint is quite different to the real one.

Couldn't agree more regarding Watkins

All sides have members of their side that are renowned for being "Go to players"
We have been blessed recently by two of the best ever IMO in Senior and Lauitiiti and whilst they were in their prime they both had the ability to produce something out of nothing when given enough quality ball and defenders simply didn't know how to defend against them

IMO we have probably the most talented player in SL at present in kallum Watkins with his ability to beat a man just with his footwork alone, How dangerous would he be if he was also given good service whilst he was running good lines and into gaps too

Pity we can`t swap Burrow for Clarke at Cas and maybe throw in our ace up the sleeve and let them take Kirke.

Absolutely. As I have said before, McNamara gets more out of Watkins than we do. He is almost unplayable near the opposition line, he draws so much attention he creates space and if you don't double up on him he scores.
Moon on the other side needs to learn how to run straighter and maintain the space outside him - he is a strong, dangerous runner and he needs to use the attention he attracts to put Hall away properly.

We also have no left sided ball handling back row. For all the trouble he could cause Hock would fit there, maybe the Leeds culture could have rubbed off on him.

Hauraki would also fit the bill for a ball handling back rower (although not neccessarily on the left) but unfortunately the coaching set-up at Leeds couldn't get it out of him when they had the opportunity.

I once queried the McNamara selection of Brett Ferres referring to him as a SL standard rather than an International standard player - Cas' equivalent of Carl Ablett at that time - one of them has improved their game out of sight since then while the other continues to stagnate as a player.
