The Tennessee Vols suffered their worst loss of the season on Saturday, falling 107-79 to the Kentucky Wildcats in Rupp Arena.

It was the most points Kentucky has scored against an AP Top 25 team since scoring 107 against Vanderbilt in 1994 (per the associated press).

Tennessee is now 11-5 on the season. They've lost three of their last five games.

After the loss — during the loss if you're active on social media — there was plenty of criticism for Vols head coach Rick Barnes.

Most of it centered around whether or not he's living up to his rich contract. Barnes makes around $5 million a year, which makes him the No. 5 highest-paid coach in college basketball.

Are the Vols getting top five results from Barnes?

One sweet 16 appearance since arriving in 2015 suggests the answer to that question is no.

Barnes is 131-75 at Tennessee. That's a 63 percent winning percentage, which is in line with Barnes' career winning percentage of 65 percent.

In other words, I wouldn't expect different results from Barnes anytime soon.

Rick Barnes is definitely in decline

Here's an even more concerning stat, though.

Barnes' record at Tennessee would be even worse if not for former Vol standout Grant Williams, the 2019 SEC player of the year.

It could be argued that Williams propped up Barnes' record much like Josh Dobbs propped up Butch Jones' record.

Barnes is 73-28 (0.722 winning percentage) with Williams. He's 58-47 without Williams (0.552 winning percentage).

Barnes has barely been above average without a transcendent player like Williams.

Even more concerning is that Tennessee has elite championship talent. Barnes has recruited well in recent years, landing five-star players like Kennedy Chandler, Brandon Huntley-Hatfield, Jaden Spring, and Keon Johnson.

Yet the Vols' winning percentage is only 58 percent over the last three years — 7 percentage points lower than Barnes' career winning percentage.

Here's another comparison: Former UT coach Cuonzo Martin, who took the Vols to a Sweet 16 in his final season in Knoxville, was 63-41 during his carer at UT (0.606 winning percentage).

Without Williams, Barnes has delivered similar results (while making over $3 million more than Martin).

Now, what does all this mean?

I think it means it's time for Barnes to retire. The game has changed a lot. It's why coaches like Roy Williams at UNC and Coach K at Duke decided it was time to get out.

Barnes is from that same era of coaches.

I like Barnes. He's been great for Tennessee. The program is in a really good spot. It's just underachieving. The Vols should be getting better results for the salary they're paying Barnes and the talent on the roster.

I don't know where Tennessee goes from here. But this is as good as it's going to get under Barnes.

The good news is that UT has an athletic director in Danny White that has proved he can bring success to programs. Vol fans need to trust that he'll make a great hire when the time comes to replace Barnes.

Now it's just a matter of figuring out when that time will be.
