Excellent - so we have found the question

(i was lost for a few days, thisa would have been up sooner, but for RL)
Had Gandalf recognised the One Ring before Bilbo had returned to the Shire, would the Ring have been destroyed before the Rise of Sauron
On behalf of my time, I will open. There happens to be very little evidence from the novels, for this is a hypothetical question - but looking at some of the letters from tolkien, we, the opposing team (come on guys, we need a NAME *looks at team*) are proving this this statement could indeed be false.
Look at the possibilities. Sauron was indeed at Gul Duldur, But as this is hypothetical, why cant we simply assume that he stayed in Mordor. That Gandalf, instead of actually having to face against him, had instead stayed with the mission and helped the
dwarves (and indeed bilbo). He could have found out, just like the rest of the dwarves, at the same time as them! So Sauron, in this time, could quite easily have built a much larger strength in Mordor, protecting mount Doom!!
Also, the reason why
Frodo succeeded was, in some respects, due to the fellowship. Gandalf could quite easily have spent TIME finding a suitible group, but even without the "strength", Sauron still had the ringwraiths, at his disposal, in mordor which would have been more then adequate protection from the "destruction" of the ring.
Ok, this is just an openor, so my team, back me up!
