Based on experience and a lack of Campo I fear we'll get off to a bad start. The Raiders always have been a cold-weather team (for obvious reasons) and we always struggle in the opening, warmer months - that will be further accentuated this year with our forward pack being so massive.
Having said this, I genuinely believe that this is the year we can go all the way.
The Raiders should have beaten the Tigers in the semi last year, an injury to Campo was a killer blow half way through the game, and even still we should have pushed it to golden point if not for the shock missed penalty goal by Croker. If we had of won that game, only the Dragons could have stopped us - and our record against them is very well documented.
So to answer the original posters question as to why the Raiders are rated so highly this year - because at the end of last season we were one of the best teams, and our team has gotten stronger since then. Put those two together and you'll work it out.
