What single factor is key for the Skins this year?

[PIG#1]

in my opinion it all starts with the head coach.the sucess of this team rides on his shoulders.zorn has alot to prove in this league and to dan synder.so far so good but we shall see how it all works out come sept.can he make jc the qb he thinks he can.not getting a few more free agents in,the draft.will his system work.i certinly hope so.to add one more thing that worries me is the defense.it's getting old.bottom line.
