Maric, Douglas and Porplyzia in the best 22 for mine.
McGregor may well go ok at CHB for some or much of the season, but will get found out at some stage for lack of mobility!
Forward line provides plenty of options, but looks easily closed down in tight games or by the better teams in the comp, the Ruck is very suspect.
For the Crows to have a reasonable year (and I think thats the best possible result they can achieve) they will need a good run with injury (granted, as many clubs will) and with the majority of your best players around 30yrs of age (or more) they look very vulnerable ... Tough year for them I think.
