Let me start with the positive as I see it:
no one has hurt the OSU defense yet. IU survived it, moved the chains when they had to and hit a couple of timely explosives but still only scored 13 points. I don't know what the blue print is for someone to really hurt this defense because we haven't seen anyone put it on tape yet. Maybe a team that could protect well enough to take deep shots on a little bit of a suspect secondary...just theoretical. Not sure anyone could really do it.
Now the offense, we had seen flashes of the kryptonite all year. IU just put it on tape for the rest of the playoff field.
OSU's fatal vulnerability is a weak IOL + QB processing under stress.
Consistent pressure+ good coverage + post snap rotation = blueprint for defensive success against the OSU offense.
ST;
Kicking under pressure just cannot go on the positive side of the ledger. Hasn't for years now.
Last night we saw IU beat OSU at it's own efficiency game. They won 3rd down battle in both phases (6/13 on offense, 4/12 on defense) and did just enough in the red zone to make OSU come away with two empty trips which is the same as 2 turnovers and they won the TO battle +2.
The two completely empty trips (vs IU at least kicking 2/3 FG's) was the ultimate fuel for the upset. You can't have that.
Day and his staff were outcoached by Cignetti and his. They were one step ahead of the OSU offense all night and broke every facet of the efficiency model OSU uses. The OSU adjustment to what IU was doing was too little, too late.
There are teams in the CFP field that fit the mold here (TT comes to mind quick) maybe some I am not thinking of yet.
Sky isn't falling but again, the way to beat this team was just just shown and it's flaws are foundational. You can't fix that IOL this late in the year.
