Right. If Dresser and staff are in their 7th year like KJ was and the program is going the wrong direction that will be bad. KJ took over a top 3 program and ran it into the ground.
Dresser is taking it over from rock bottom and trying to bring it up. Realistically going to need 3-4 years to see this take shape. Although, I expect by next year ISU is beating Drexel and Rider. Year 3 I think they are a top 20 program, and year 4 pushing for top 10.
I think your recollection may be a bit off. In 2015/2016 when the team was 10-6 they did not have a brutal schedule. They beat 1 NAIA team, and a bunch of barely D1 teams (George Mason, Chattanooga, West Virginia). They were killed by any team that was any good (OSU, Minnesota, Iowa). Their NCAA performance was artificially inflated thanks to Pat Downey. This was typical of the Jackson era. He would wrestle a bunch of cupcakes and pull 1-2 high AAs out of his a$$ at nationals to give the appearance that things were better than they were. The shell game fell apart completely last year.
What I was trying to say or what I thought I said was that just 2 years ago we were beating those 'barely D1 schools' and beating the likes of UNI, Central Michigan and Wyoming and beating #4 Virginia Tech at the Virginia Duals and only losing to powerhouses (4 of 6 losses were to top 7 teams), finishing 3rd at the Big 12s and taking home 3 medals at the NCAAs. We were very respectable at that time. And there are no 'artificially inflated' numbers at the NCAA tourney, either you win matches and score points or you don't.
I never saw a steady decline in the Jackson era, I saw a respectable program just completely fall off a cliff last year and I certainly didn't see it coming.
