Well, the last full schedule of games is over with the following results.
#1 - Clemson (12-0) beat South Carolina (3-8) 37-32
#2 - Alabama (11-1) beat Auburn (6-6) 29-13
#3 - Oklahoma (11-1) beat Oklahoma State (10-2) 58-23
#4 - Iowa (12-0) beat Nebraska (5-7) 28-20
#5 - Michigan State (11-1) beat Penn State (7-5) 55-16
#6 - Notre Dame (10-2) LOST to Stanford (10-2) 38-36
#7 - Baylor (9-2) LOST to TCU (10-2) 28-21
#8 - Ohio State (11-1) beat Michigan (9-3) 42-13
#9 - Stanford (10-2) beat Notre Dame (10-2) 38-36
#10 - Michigan (9-3) lost to Ohio State 42-13
I see any reason to change the top four so I'm thinking they stay the same. Next week are the conference championship games and Clemson, Alabama and Iowa are all playing.
#1 - Clemson (12-0) will host North Carolina (11-1)
#2 - Alabama (11-1) will host Florida (10-2)
#4 - Iowa (12-0) will host Michigan State (11-1)
Clearly the most interesting game here is Iowa vs. Michigan State. With State hovering just outside playoff territory and #5 the winner secures a birth. I doubt that either Clemson or Alabama are going to get tripped up but you never know.
I suppose Oklahoma is in since they're done with their schedule. For them to lose a spot now would make just about everyone question the sanity of the playoff committee process.
Of the teams sitting on the fringe I suspect that Ohio State has the best long shot of getting in if Alabama loses to Florida.
Assuming Clemson and Alabama win then the final four should be a non-controversial no-brainer with Clemson, Alabama, Oklahoma and the winner of Iowa vs Michigan State.
