A few things:
a) It could be pretty tough to come by every pose (even the known ones) for each player. So you might want to consider collecting just one pose for each player. That's a lot more affordable and achievable.
b) You are lucky you are not collecting 88's. It has this manager card called McGreachery which is rather tough to come by.
c) If you do choose to chase every pose, you can go through past auction results on cardtarget.com and VCP if you haven't already.
