here is my opinion about meteo at 5/8,
if you watch him play carefully he never plays before the line,he will always go to the line then try to offload ,thats why lock suits him better than 5/8,ive never seen him play a natural no.6 passing game before the line,like say,D lockyer fer eg.
Thats because Mateo right now is playing to the instructions of DA. To do the dirty work. There is no way in hell he would do the same thing at five eight. When he was at five eight in 2008, he and Riddell formed a nice little play that attacked behind the rucks. An outside ball to Mateo, then an inside ball to a runner, Luke Burt usually I believe.
Same year, Mateo also made a nice little chip kick for himself and then passed it out to Inu for him to score. Against Brisbane.
People bring up last years form when defending Kris Keating, well Mateo was also in good form up until he got injured in the same game, and he was at five eight.
Also, I have the opinion that Darren Lockyer plays more like a halfback then a five eight for Brisbane, which suits Brisbane. In the halves (and forwards too I guess) Mateo is like John Sutton. We cant expect him to be like SBW, Lockyer or who ever.
