That's what he was last season. He has a presence similar to that of Anthony Gelling.
I was surprised to see Mitch Brown in ahead of him...
Tbh I'd have played Charnley at centre ahead of Mitch Brown. Charnley is a very handy centre himself. If Charnley was at Wigan now, I'm pretty sure he'd be the starting 3/4 all year, with Bateman returning full time into the back row.
