Troy is the single biggest loss to the Tigers - as proven over the 2007 season. The article said he was fit, which is a great sign, but I would like to think he goes alright under stress tests before saying he is fit. What his big heart (and he has a ripper IMO) can now handle will only be known in the months to come. On the very positive, the time out may have assisted his ankle in ways not previously acheiveable.
With him fit and firing all season, we are potential finalists, without him we are 13-16 again. He is a classic tempo player, building it though a whole game. He has to start on the ball. That is how important not only his rucking is, but his work around the ground. Rate him better around the ground than Cox. But he has to "get into the game" to be effective - as proved by his efforts at CHF in 2005.
