If not Gus we should have someone else in place especially if we get Brees, A
As a former recovering shoulder surgery patient (torn Labrum)it is recommended that you wait 12 months before particpating in athletic events.
This is taken from a website:

A return to overhead throwing, tennis strokes and contact sports require at least six months of rehabilitation, and a full return to competitive overhead sports requires 12 months. YOur return to weight lifting is unpredictable. You may need one full year before performing activities such as the bench press and you may never recover enough to lift heavy weights.
I can tell you I was very concerned when the Jets through Chad into the starting lineup right away (everyone but the Jets knew he wasn't ready to return) , I think Drew is an improvement over Gus, but i don't want to see us throw Drew in right away if he needs to rest his shoulder, even if it means waiting till midseason of next year, do it.
I am guessing we want Drew for Long term not for a 1 year run, and if that is the case, then we need to have a backup that we can EXPECT to start the year as our Starter.
