This for me, if Horne can prove he is fit and can play against either rovers or Salford he starts at FB.

If not its a tough choice between whiting and Shaul, obviously a lot will depends on how Shaul gets on over the next couple of games.

I would much rather Whiting was on the bench because he is so versatile.

If Horne is not fit then I would probably go with Shaul at FB if he can show he is up to it between now and then.

Bit of a no brainer to play Horne at full back if fit there is no hiding place at full back and Wigan would really target shaul if he played wouldn't be fair on the lad really after so few games

My point was/is that Horne would be the ideal replacement and after that it would be Whiting. Of course we lose something off the bench but fullback is too important a position to take risks.

If Shaul plays prior to Wembley then he would need to produce some really top and assured performances to get the nod as Wembley is a huge game for any player, let alone a player who has played only 4 SL games. Experience would always win over for me and I reckon for Gentle.

Wigan are arguably the best team in the comp and they know how to exploit weaknessess. He would get targetted and that is why I would be unlikely to pick him.

By playing shaul you'd be pinning a target on him. He'd be subject to everything. Wigan would hit him with everything. Not saying he's guaranteed to fail but it's a lot to ask. Horne we know is safe but more so is safe to say gonna be better at link play/releasing others/playing as a third pivot, and we could certainly use that. Shaul maybe a better broken field runner but when looking at the bigger picture if you broke it down into categories Horne would win hands down on most.
All that said Jamie gonna get a run of at least 2games to show what he's about so hopefully he'll give gentle a reason not to just rule him out.
Good luck to the kid.
