Everyone's attack is a bit rusty at the start of the season. It takes a while for the match fitness and match awareness to come up to speed; with a redesigned back-line from last year (Hoffman back, Copely gone, Norman instead of Lockyer, Beale pushed to the wing- only Wallace, Hodges, Reed and Yow Yeh have kept their slots) it is going to take a while for it mesh.
But the signs at least are there, and every game- even last week's loss- has shown some improvement. Against the Eels, pretty sad. Against the Cowboys, we were able to put on the points quickly before a very uncharacteristic error cost us the game with no chance to reply. This week, the team had faith in their ability to score and were willing to put in the hard yards to get the result.
It might be another two or three rounds before the clockwork is operating properly, but until then the Broncos have demonstrated they have the stamina to stay in a game and the will to knuckle down and grind it out.
You can afford to tread water on attack if your defence is good, but not for too long. Happily, the Broncos have a stern defence and are just working on getting the other side up to snuff.
If they're still staggering around like this at round eight or ten it will be trouble, but I don't see that happening.
So far as McCollough goes, while he isn't exactly setting the world on fire the team does look a lot more dangerous with him out there than it does with Hunt. I would be happier if they decided to simply get rid of one or the other, as switching over stifles McCollough and Hunt would probably do about as well if given the full-time gig; it also frees up a bench slot, and when you're juggling Gillett, Te'O and Glenn with Parker to return that gives you some breathing space. A bench of Te'O, McGuire, Gillett and Hala in prime form would be an absolute nightmare for opposing teams.
