And Genia and Horwill are both very long odds to be in the starting side. Which leaves it open again. And we come back around to Hooper.
I think that's a pretty uninformed comment that doesn't really consider the factors at play.
Firstly the differences in the packs white and genia play behind. Though for the record, I'd go white.
As for Horwill you have to consider the competition.
Simmons is the only genuine line out centric LH lock so he'd be close to a certainty for one spot.
Jones has been immense and extremely effective for the Rebels. But he isn't a great line out technician. The line out would be weaker for it to replace Simmons so it likely rules him out of a LH lock position.
He also also been best effective used as a slightly wider runner (I believe Lee Grant calls it the loose tight, or the tight loose) with his running being a big part of his work rate. Will this translate to the tighter runner whose work is made up more of hitting rucks and tackling?
As a player who is physically a 6 and being played at lock, there has also been questions over his scrummaging. Would be be detrimental to the scrum as a tight head lock?
Carter is probably the best comparison. Line out is slightly inferior but still very good, and better around the ground at the moment. Slightly smaller so could this count against him?
Skelton. Likely not to start and everybody would agree currently, he's an impact player.
Not saying Horwill is better or that others won't start, just saying to say he is long odds to start is quite wrong.
