Hello mate,
West Coast is lots of screen passes, slants, RB flares - basically passes with little risk involved. Chad Pennington ran it whilst at the Jets. As he has a weak arm and his long passes tend to sail, this is what you can expect from the fins in '08, coupled with a power running game. It's difficult to execute though as 3-4 defensive linebackers are so athletic these days, but when the Bill Walsh invented it, most defenses used a 4-3 with huge linebackers.
