I think it's easy to forget that in the last squad, it was Mcreight that Samu kept out. If Mcreight is in, and with the rise of Gleeson - I can see Samu being squeezed which is a shame. But they can't afford to carry Hoops, Samu, Gleeson and Mcreight in 4/6 spots. Not enough range there.
IMO
Hoops, Gleeson, Samu & Mcreight are going for 3 spots
Wilson, Valetini, Leota, & Holloway are going for 3 spots.
Hanigan is liked by Eddie but Holloway has him beat as a lock/6 and Swinton (a personal favourite of mine) would have to kill it on his return to battle with Leota and Wilson for a spot in the 'finalist 4'.
