Others - Arniel Gane, Urag Gro-Shub, Enthir.
asrniel is a Researcher (and powerful Mage in his own right.) Urag is a librarian, I don't know if he can fight, or use magic, but he threatens to have you torn apart by "Angry Atronachs." I don't think he charges late fees. Enthir it the TG fense for Winterhold. I don't know what he actually does there, or is supposed to be doing when he's not working shady deals out of his room.
To really know how this would turn out, you would have to figure out the abilities of each member of the College. Are they all on equal footing? Do they possess equal strengths in every school? If you assume that they do, or at least the teachers and higher are Expert/Master proficiency in all schools, then hands down the College wins.
Taking only the 6 teachers plus Savos and Mirabelle, if they can all use Silent Casting + Muffle + Invisibility + Mass Paralysis, what hope does anyone have? All spells can be started while invisible, you only become visible once the spell is cast, too late for any opponent. What if they also have Twin Souls, adding an additional 16 combatants to the College? What if you factored in Master level Illusion spells like Mayhem? Or Expert level Illusion spells like Pacify?
I've seen most of them in action, and not just watching the tube above. None of them use anything even close to this OP combo. Drevis probably could, but whenever a Dragon shows up, he's gone. (I'm pretty sure he has both Quiet Casting, and Whirlwind Sprint!) I pretty much count him out of every fight, because he just doesn't. In other words, just not gonna happen.
Tolfdir uses mostly Falmes, and I think Stoneflesh, but I've seen him Ward, and drop a FA. Aren apparently favors an Iron battleaxe, don't ask me why. I've also seen him dual cast Ebonyflesh, which is pretty damned good protection as his assumed level. I bet he could stnd toe to toe with Vilkas, and at least let him know he'd been in a fight. He usually drops Frost Atronachs, I've seen him throw a Stormy, and he's gos a staff full of them. Faralda is a Desruction Mage, at least the equal of Festus Krex, those are Master Robes she's wearing. Leave her alone.
Mirabelle uses basic Destruction, (Flames, and Shock, usually) Somethingflesh, and Wards. Collette wanders around all night randomly casting wards Flesh Spells, turn undead, and other things. She's a cloud cukoo lander, I have no idea what she'd do. Ninya is a baby Faralda, for all I know, she's her jealous daughter, or kid sister. Expert. Arniel Gane is a badass, even after death. He could probably take on the Circle by himself in the right battlefield.
J'zargo is Destruction, ranging from Apprentice to beyond Master, depending on the Dragonborn's level. (He can reach 81, but only under specific situations, nearly nothing but destruction magic.) He also favors Heavy Armor. Brelyana is a pretty effective all around Adept. Surprisingly ballanced, and probably the best follower of the three. (Not to mention Fire resistance.) Orthorn is a mediocre mage, Alteration, and Destruction, frost mostly. I'd rate him Apprentice.
