Zenger has already stated that Beaty will return next year.
In the short term, I get that it sucks because the W-L record hasn't shown anything for Beaty to return.
Personally, I think this is the right call for the big picture view. We can throw the current scholarship numbers out there which makes it look like KU is there or very close, but the reality is KU is still 2 years away from being caught up. Beaty inherited less than 40 scholarship players during the 2015 spring. Today, the number is somewhere in the upper 70's right now. 2015 was a small senior class like this one and 2016 was a large senior class (27 players I believe). Let's say KU has graduated somewhere between 35 and 40 seniors the past 2 years. Beaty has brought in 62 players in the 3 recruiting classes he's veen apart of. Do the math, that means KU is still at about 60 scholarship players that were recruited as scholarship players and somewhere between 15-20 walk ons that have been awarded scholarships at some point.
That means David Beaty inherited a roster with D2 level of depth and has now built to FCS depth. It also means we're still 2 years away from being caught up and having FBS level depth. If you fire Beaty now, you destroy this recruiting class and keep KU at FCS level depth whole expexting the next coach to succeed with FCS level depth for at least 2 years.
Keeping Beaty for 2018 is the right call because it allows him to build a full recruiting class this year which should put KU somewhere around 70 true scholarship players. Not perfect, but a much better situation to give Beaty's successor than to bring a new coach in with only 50 true scholarship players which is only about 10 better than what Beaty inherited.
I know it will be frustrating next year because 1 or 2 wins appears likely again, but I will go through that if that means Beaty's successor has a much better foundation to build upon than what he would have going into 2018.
