Katz misses the main point that it is not OOC but rather overall body of work that matters. If you are a top team like Cuse is, Boeheim is wise not to get overly aggressive in OOC scheduling. If your BE may end up on the bubble, then adding some better OOC teams to the schedule could be the difference of NCAAT or NIT.
Using Dickie V’s rankings and giving 0.5 credit for teams that potentially could face one another in a pre-season or Holiday tournament, the toughest overall body of work rightly or wrongly is all BE teams in top 5, with two BE and two B10 teams tied for 6th-9th, and two more BE tied for 10th -14th:
Top score is 15 and all 16 BE teams score at least 11.0, five BE teams without ever playing anyone in top 40 outside of BE.
15.0 Louisville
15.0 Georgetown
14.5 St. John’s
13.5 Notre Dame
13.5 USF
13.0 UCONN
13.0 Cincy
13.0 Michigan State, the first non-BE team
13.0 Indiana, tied
12.5 Purdue
12.5 K-State, the first Big 12 team
12.5 Villanova
12.5 Maryland, the first ACC team
12.5 Rutgers
12.0 Ohio State
12.0 Syracuse (only non-BE is Florida, then VA Tech, Okl St and NC St)
12.0 Kansas
12.0 Marquette (all due to BE, best OOC is Wash, ole MS and Drexel)
12.0 West VA (best OOC is #40 Miami-FL, then K-State and Kent St)
12.0 Tennessee, the first SEC team
12.0 Oklahoma
12.0 DePaul (all due to BE opponents, best OOC is Minn, ole MS, Dayton and Fairfield
11.5 Texas
11.5 Michigan
11.5 Missouri
11.5 Oklahoma State
11.0 Duke received a 9 on that site for Schedule and Cuse received a 4?
11.0 Northwestern
11.0 Pitt (all attributed to BE Opponents, best OOC in TN, then Duquesne and James Madison)
11.0 Seton Hall (again all BE with best OOC Northwestern, VCU and St. Peter’s)
11.0 Providence (again all BE, with best OOC teams like BC, Iowa St., N Iowa and URI)
Not surprisingly then, weighting Dickie V’s top 10 @4, teams 11-20 @3, teams 21-30 @2 and teams 31-40 @ 1, the toughest overall body of work belongs to BE and SEC-East teams, and Cuse is even higher in the overall list due to BE strength relative to the other conferences in Dickie V's (and everybody's) top 40.

So Katz should reserve the ratings of 4 and below for these last 10 schools, not any BE teams other than relative to one another.
