Duke has been more consistently dominant.
Since 1985 they have only missed the tournament 1 time in 1995 and besides that they only below a 4 seed 2 times in 1996 they were an 8 seed and in 2007 they were a 6 seed.
Every other year they have been a top 4 seed.
I do think JB is a better coach with talent though. JB is the better defense coach and would get them to play better defense. JB doesn’t get those players to come to Syracuse like K does to Duke.
K is a great coach himself but he hasn’t constructed great rosters to support his superstars.
I wish we could have one top 10 player a year and not multiple like Duke.
If we want to compare JB and K the most accurate time period would be the mid to late 80's. K wasn't quite K yet and JB was recruiting at an elite level before the first sanctions.
Starting in the '80-'81 season, K's first at Duke and our second in the Big East Conference, neither team made the NCAA tournament that year. Ending in '89-'90, the last before K won his first NC, and was considered by some a coach that couldn't win the big one, and the year before we lost to Richmond, signalling the end of our first elite era.
JB got back to the tourney first in '83 with K going in '84.
JB made the final game 1 time, the elite eight 1 time, and the sweet sixteen 2 times.
K made the final game 2 times, the final four 2 times, and the sweet sixteen 1 time
Seedings were pretty similar.
JB - 2 seed 4 times, 3 seed 2 times, 6 seed 1 time, and 7 seed 1 time. Avg - 3.38
K - 1 seed one time, 2 seed 2 times, 3 seed 3 times, and 5 seed 1 time. Avg - 2.71
JB had two 30 win seasons and seven 20 win seasons.
K had one 30 win season and six 20 win seasons.
During that era when talent levels were similar, it looks like K had significantly more success than JB in the tourney with regular season success tilting slightly in JB's favor.
