2lab - apologies if I'm teaching your grandma to suck eggs and you actually happen to be Mr Bloodbowl (Croatia, '03) but put a treeman in your starting team. He needs as much time as possible to get good. And a block-free LoS. Also, go light on the re-rolls (no more than 1) - you've got enough AG and skills on the specialists to cope.
And, never ever brawl. Ever.
