I would have thought the one person whose regular first team place is under direct threat as a result of this is the much ( and often unfairly) maligned Frawley. As you say, Connor's field kicking has far more variety and in general he's a much more creative player. So unless we do intend to play him as a centre, and I don't think we will, Connor will be competing for a place in the spine. His goal kicking gives him an edge. Will be fascinated to see what transpires.

I think Connor will be a replacement for Momo.

That could very well the case, but I don’t think he'd be an upgrade. He's not bigger, not faster, not noticeably stronger. Just think that if Mom leaves Arthur will want a player that can make a real difference in the 3/4s. The type of player Fusitua should have been but never was. I guess there's an argument for using a quota spot on a 2nd rower, but my gut feeling is that he'll plump for another back who can really get the sets moving downfield.

Sivo would be a good shout especially with Paramatta paying some of his wage.
Personally I prefer Handley on the wing as opposed to him playing centre as his defence isn`t that good.

I'd say Connor would be an upgrade on mom, I'd argue while not faster he's quicker, while not 'bigger' he's more competitive and far more creative. I think he will be used at centre with utility value and I hope he thrives at the club under Arthur
