I certainly wouldn't put the lad in the same bracket as Watkins - I think he is / will be close to Tomkins as the 'special one' in SL - he has everything!
The comparison I would make is with Hardaker - not saying he's there yet, but neither was Hardaker when he joined Leeds. I do think he has all the attributes to be the best backline player at BV!
I have to laugh at the Hull fans though - sorry guys, but you can't blame Agar when it he who has signed him - for 3 years - despite the relatively small amount of game time at Hull - and I reckon it will soon be seen as one that slipped through the (fishing) net - and that's without trauling through your board!
