I'm not sure Tolman is really a good fit, but maybe...
Solid workrate, but little impact. Would only really be useful if we were moving either Lillyman or Mannering out of the middle (or out of the club, in the case of the former). I rate him as a guy who is very similar to Lillyman - gets plenty of work done and is a good 2nd or 3rd banana, but needs the right pieces around him... otherwise our middle will get dominated.
Brenton Lawrence interests me a little more (Chris Heighington to a degree also). NAS too (assuming he's still off contract) - but he's very rough still.. remarkably mistake prone and I don't trust us to coach those down. If we were taking a guy who is a super strong runner but still a rough prospect I'd rather we went younger/less expensive - George Fai from QLD cup (Broncos contracted this year). His defence has gone into wtf mode for the past few weeks but otherwise has been hugely impressive - averaging over 50 minutes, big metres, loads of tackle breaks (and some offloads) and relatively few errors and penalties.
