Let's take a quick peek at every conference race, which impacts the bracket from the very top to the very bottom. Let's take inventory.
America East: Stony Brook and Vermont are at 3-0, and everyone else already has at least 2 losses (UMass-Lowell is ineligible, remember).
AAC: Cincy is the only undefeated team through 5. Memphis and UConn 2 back in the loss column.
A-10: 3 teams undefeated through 3 games: UMass, St Louis, LaSalle. Hey, LaSalle, I remember you! Their at-large profile is mostly junked at this point, but they can throw a wrench into the bubble picture in this conference.
ACC: Syracuse and Pitt lead at 4-0. Long way to go.
A-Sun: Mercer and FGCU at 5-1 lead. UNF and Jax one game back. This could quickly escalate into another 2-horse race.
Big 12: Kansas is the only undefeated left at 3-0. LOOOOOOOONG way to go.
Big East: Creighton 5-0, Villanova 4-0, Xavier 4-1. Separation is the key to a high seed for Creighton and 'Nova.
Big Sky: Early and jumbled (N. Colorado, Montana St, and N. Arizona on 4-1, Weber St on 3-1). We'll know more later.
Big South: Everyone's played 3 games. Everyone's already lost. Say hi to the play-in game, Big South.
Big West: It's still early. UC-Irvine and Cal Poly at 3-0. Check back later.
Colonial: Delaware 3-0, Towson 2-0. It's early here too.
CUSA: You know, for a 16 team conference with everyone only playing 2 or 3 games so far....there's only 2 undefeateds (LT and ODU). This is going to be a hot mess all season long.
Horizon: Green Bay is alone at 3-0 at the top. I'm expecting a hypercompetitive league.
Ivy: Not even underway for half the league yet.
MAAC: This is one conference well deep into conference play. Manhattan 6-1, Canisius 5-1, Iona 5-1. This is a kind of weird conference where the bad might be really bad and the good might be really good. I expect many postseason teams in this conference.
MAC: Akron is left as the only undefeated at 3-0. Over in the MAC West, Toledo, EMU and WMU are at least making that half look decent for once.
MEAC: Early, and 4 undefeateds, and 3 winless. More extremes in this conference.
MVC: Wichita on 5-0. Well, so is Indiana St. But we know what's happening here.
MW: SDSU on 4-0. Nevada is the shocker, sitting on 4-1. It won't last. For now, they're just getting in the way.
Northeast: Robert Morris at 3-0, everyone else has absorbed a loss. Future probably isn't looking too bright for the conference.
OVC: Murray St at 5-0, last undefeated. Figures, in a year they were supposed to fall back a bit.
Pac-12: Cal has joined Arizona in an undefeated start.
Patriot: Boston and American(!) on 5-0, leading. Army at 4-1. A bit of the changing of the guard early in this conference. Unfortunately, this will likely come with a 16 seed in March.
SEC: Tire fire. Florida and A&M(!) on 3-0 lead. Still plenty of time to see this conference burn.
SoCon: Chattanooga 5-0, W. Carolina 3-0. Some bad teams, it looks like, which means potential for separation at the top. It's also their only hope at missing the play-in game.
Southland: SFA is 5-0, a bunch of teams with 1 loss right behind, we need more clarity later.
SWAC: Southern 4-0. Who cares?
Summit: Still early, but IPFW and South Dakota lead. NDSU absorbed a loss already, oops.
Sun Belt: Georgia St (4-0) is the last undefeated? Ok then.
WCC: Gonzaga 5-1. Yawn. Hey, did you konw all 10 teams already have 10 wins this season? They might monopolize the CBI this year.
WAC: New Mexico St actually trails by a half-game in this conference. Good God.
