I would agree we're not as strong without Cassidy and Gibson, the results of the last couple of months by comparison to the start of the season demonstrate that. Personally, I'd say Gibson is actually the bigger loss. Greg Blundell did mention him in the physio column, which implied he'd be ready to start training soon, so maybe ready next month...
Turning to the game, we've done well on recent trips to whatever Brisbane Road is named now. If we were up against the same side as the season opener, I'd feel very confident, but Orient have moved on considerably. No ex-player links as Chorley and Brunt have moved on. I doubt that their JPT 2nd leg will be weighing much on their minds and expect this to be a tough fixture.
Rovers likely to be as last week, save Stockton replacing JLAA. If we're to stay top, it's a game we'll need to win as the two teams below have fairly comfy looking home fixtures. I don't believe we'll manage that and reckon 1-1.
