There were whispers at the start of the season that Dragons had an easier schedule and were jumping on teams that were not at their best. It could be argued that now that these predictions are coming true, Dragons on sixth on the ladder and had a less then impressive win against the Knights. Dragons are suddenly looking like a team that a vulnerable, a big change from where they were earlier in the season.
They've beaten the Tigers x2, Warriors x2, Knights, a Thurston/Coote/Scott/Granville-less Cowboys side, and an out-of-form Panthers side in Round 1.
Once decent wins have come against Manly and Cronulla (who have been flat this year, and pulled out some lucky wins at the death).
And they've actually only got 2 games left against top-8 sides (Broncos and Manly)...
So I'd say they've have a ridiculously easy schedule.
1x Game against Melbourne, Nth Queensland, Brisbane, Roosters, Raiders, Rabbitohs. That worked out well for them!
Mind you, the key to making the 8 is winning the games that you should (i.e. against the teams below you) and they are doing that pretty well.
