I don't know about 3-15 or 4-14 considering that this team could arguably have beaten Texas A&M, Mississippi St, Vanderbilt and South Carolina to this point. I'm not saying that all of those would have happened, but Georgia either outplayed those teams for significant stretches or was dead even with them for long periods. Interior defense, rebounding and additional offensive flexibility have all suffered. The presence of its two best forwards would certainly make a difference on both ends of the floor.
Go ahead and remove two starters or a starter and his chief backup who also plays significant minutes from ANY team in the country. What would happen? Surely teams like Gonzaga, Baylor, Kansas, Auburn, etc. would probably still be really good. But to think that they wouldn't suffer some is irrational. It's not an excuse. It's reality. Georgia had little margin for error to begin with. Then it lost arguably its two most experienced, most physically built for SEC players.
