Can't see Spencer splitting time with Gawn. When you have an asset like him you're not going to diminish his output. Spencer did ok in meaningless JLT games but it's a different story when the real stuff starts.
You have Goodwin a first time senior coach so it's now his head on the chopping block. He needs results so you'd think he will play his best team and not tinker with it. Just think what would happen if Spencer played taking Gawn's rucking time and the losses came. The demon fans and the media would be in uproar. What does Goodwin do then? Revert back, then the question of course is why did he not start like that which would lead people to query his level of competence. I'd be very surprised if he's got the balls to go down that road. Maybe a senior experienced coach who has had success could get away with it but not a new one.
For me, paraphrasing a well known saying, it's "All the way with Gawnstein".
strong analysis....lets see if round 1 teams say a diff story.
