IMO, the SEC West is still the best division. First of all there isn't much competition. The B10 East powers are OSU, Mich, PSU, MSU, then Indiana, Rutgers, Maryland.
OSU: struggled, could have lost, to barely decent TCU; beat PSU by one; struggled, though no chance of losing, with Indiana; struggled, though no chance of losing, with Minn
Mich: lost to ND; almost lost to NW who lost to Akron and was manhandled by Duke
PSU: went to OT at home vs App State, lost to MSU who (see below)
MSU: almost lost to Utah State; lost to ASU; lost to NW
The only positive: Maryland beat Texas. That's it. That's the only feather in their hat. Just not impressed.
The SEC West:
Alabama: really has done nothing of note other than spectacularly crushing their weak schedule. Beat decent-good A&M by 22, decent Mizz by 29 and almost decent OM by 55? All 7 games essentially over by halftime.
LSU: spanked overrated Miami
A&M: could/should have beaten Clemson at home but lost
AU: beat decent-good Washington; they have since imploded
MSU: crushed poor KSU
OM: convincingly beat decent Texas Tech
Ark: like Rutgers
So, the SEC West has not done a lot, but it's much more than anyone else that I'm aware of.
In summary, the B10 East does have 2 teams in contention for the CFP, but would they be if they were in the SEC West with Alabama? IMO, no, nor would anyone else. It's almost like all of college football is down but Alabama (and Bama's D, though better than many of its fans realize, is probably thinner than any since 2007). I'm sure someone will change our perception before the year is over - I guess.
