He's always said he wants to hook. And why would we want to compromise on possibly very good in the back row when he's potentially superb (stopping short of GOAT atm.....) at hooker?
All depends on those pesky basics.
Try to put Sarries cheque book out of your mind, but just remind me which 2 of those clubs have won the last 6 Premiership ***les. Or which 2 have won 4 out of the last 5 European ***les. Or which team won the 19 RWC for that matter.
Its not an either / or question, or at least shouldn't be but I think it largely is for Eng. Good teams can flex their styles, but you're not going to find many successful sides that don't attend to the basics and don't have a healthy dose of pragmatism. Knowing when to flick the switch and being able to do so is one of the key differentiators of the best from the rest.
