It's a he, and no- no pressing at all. I've been through this myself. I don't think ANYONE has illusions of building ANY pec while slowly rehabbing a shoulder. I went 8 months without pressing - right around the time I joined your board actually - and it drove me NUTS. I was limited to flyes and side laterals. They are indeed better than nothing, but mostly to maintain what's left of the stabilizers and bring a little extra blood supply to the area while it heals.
Dumbbell pullovers hit lats and pecs. I thought these might do the same, but with perhaps less rotator cuff strain since you're not reaching back over your head so far.
