No, the same can not be said of the SEC.
These days, the B10 truly is 3 good teams and a bunch of Vandys. Even Wisconsin and Michigan State, which were once at least on par with, say, Ole Miss and Florida, have become very weak.
Here's kind of how the SEC has multiple tiers that the B10 is missing:
Top Tier : SEC 3 (Georgia, Bama, Tennessee) ... B10 2 (Ohio State, Michigan)
Second Tier: SEC 1 (LSU) ... B10 1 (Penn State)
Third Tier: SEC 4 (Ole Miss, South Carolina, Florida, Miss State) ... B10 0 (none)
Fourth Tier: SEC 3 (Kentucky, Arkansas, Auburn) ... B10 3 (Mich State, Wisconsin, Iowa ... and I feel like I'm being generous to two of them)
Bottom Tier: SEC 3 (Vandy, Mizzou, A&M) ... B10 8 (Maryland, Indiana, Rutgers, Purdue, Illinois, Minnesota, Nebraska, Northwestern)
That entire bottom tier are Vandy-weak. A&M is only there temporarily, probably. We'll see if their utter program meltdown lasts longer than just this season. Unlike A&M, Nebraska seems there to stay. Purdue could bounce back, some day. Maybe not. Northwestern had a few good years, but those are over.
The B10 is just 3 good teams and a whole bunch of Vandys (spread is 2, 1, 0, 3, 8)). We at least have a healthy tier system (3, 1, 4, 3, 3 is a pretty nice spread).
So no, the same can't be said of the SEC.
