It's interesting that Wigan's first choice hooker was displaced at Leeds by Jarrod O'Connor, who reverts to being our back-up. I liked Leeming a lot at Leeds, but he seemed to go better when played in the halves. IIRC he directed our attack well in the middle of the field, but the outside backs were poorly served. There are also big question marks over his defence (led by Wane, amongst others). A bit of a risk for a first choice spine player for a top 2 club.
Likewise, I was amazed to see that Warrington have re-signed Dwyer, another deeply flawed hooker. They will struggle if they rely on him, although he does bring the x-factor.
