You keep saying the right thing, then missing the point. It is more important to shoot a lot of FTs than it is to have a high team FT%. You are literally inches away from getting it,
The most important stat in basketball is points per possession... both for and against. You literally cannot lose a game in which you score more points per possession than your opponent does.
Generally speaking.... 1.3 PPP and above is a very good offensive number.
A 75% FT shooting team will average 1.5 PPP for every possession in which they go to the line. (yes, some possessions will only have 1 FT.. others will have an offensive rebound to extend the possession... etc. It evens out).
An 80% FT team will score 1.6 PPP when they are fouled. That's a very good number, and so the opposition will almost ALWAYS do better to not foul that team - fouling becomes a negative expectation for the defensive team.
A 60% FT team will score 1.2 PPP when they are fouled. That's makes it much less risky to play a tight, physical brand of defense... .because fouls won't hurt you as much.
If Clemson was a poor FT-shooting team against Louisville, then it would've been a good defensive strategy for Louisville to play tight physical D... because it would lower Clemson's PPP from the field (more turnovers, more contested shots) and when fouls were called, it would've have hurt them as much.
Louisville goes into the game tomorrow night knowing that.... if the refs continue to call the games close as they have.... they can't get away with their physical, tight defense that they've been historically known for... because sending Pitt to the line will likely result in a 1.6 PPP - which is something Louisville would only be able to overcome if they shoot lights out themselves.
So Louisville has to pick their poison tomorrow defensively.
1) Play their normal tight, physical, pressing D and hope that either A) the refs "let them play" or B) Pitt has an off night at the stripe..... or.....
2) Back off a little on D to avoid fouls.... and hope Pitt has an off night from the field.
The postgame comments of both Gregory from GT and Brey from ND made it clear that both teams were in a defensive conundrum. They couldn't foul, because Pitt would kill them at the line... and they couldn't sag on D, because Pitt was lighting it up from the field. Both teams felt like they had to score almost every possession.
