How critical is Buddy Franklin's good form for the Hawks to be a premiership contender?

Normally I'd say no but in the Hawks case I'd say yes because Hawthorn (other than Franklin) have a pretty small forward line, especially when Roughead moves into the ruck. It's very strange, now that I think about it, who are the Hawthorns forwards? They seem to have ALOT of midfielders that drift in and out of the forward line like Rioli, Bateman, Young, Lewis but they are not actually key forwards. Even Franklin can be a midfielder if he wanted to!!!
