I am a little bit confused by your reply mate. I was saying that the opposing ruckmen would be better of playing against a team with 1 ruckman than a team with 2 (Obviously dependant on the quality of ruckman/men). A team with 1 ruckman is good for fantasy purposes (because like you said that ruckman carries a heavy workload) but i believe that teams with only 1 ruckman tend to allow more points than a team with 2 ruckman.
Well then we are arguing different points. I think you are kind of right but not necessarily. Some dual ruckmen work well as a combo (Bulldogs/Port) Some just suck (Hawks/Dees). I don't really care for an argument, my theory is to spend the absolute minimum on rucks (this year had Jacobs/Pyke) and spend the savings on gettting good rucks (this year Cox/Jolly).
Here is some random math. Lets say you pick 3 rucks who average 75. By your selection method you average 85 for your two ruck positions. Over 22 rounds you score 3,740. You could also take Cox and another elite ruck who average 100/90. That's 4,180. You can factor in 4 donuts without a back up and still come out ahead. That's just me.
In my five years playing DT i have never started a rookie, and try to avoid picking them for my bench as well. That's simply because i don't profess to know anything about them and i don't pretend like 'i know it all' either. I will only pick a rookie in my best 22 if i have seen them play conistantly in the flesh. I just stick to what i know basically, and therefore i stick to picking the players that i have seen play at AFL level.
To be brutally honest, and controversial, i think filling your team with rookies (and guns) is a pretty weak way to play dream team. To mine eye, it is basically saying, "I concede that i am incapable of picking a starting 22 that is potentially good enough to be my finishing 22." I'd definitely prefer to try and get a sensational starting 22 and not have to worry about trading except for injuries, then to start with a team expecting to trade 25% of your players.
So in the last 2 years you've never benefited from Palmer, Dalzeill (for his breif close to 2008), Rich or Anthony? That's odd. Ever read a report on u/18 championships? Ever watch a game on fox? Did you hear that Rich was dual WAFL preimership player? There are some simple facts that point to good DT rookies. Ignore them if you want.
