The following site says something similar. Hood.
Nice music on the site.
Some believe he was mad at his men for allowing Schofield to escape from Spring Hill to Franklin.
I've never tried to trace down the source for the claim, but I wonder if it actually came from something Hood said. The problem is compounded by his gross incompetence; was it disciplinary, or just a stupid move? Hood's career was pretty rife with the latter, and it would be no surprise to learn that his men would generate rumors like this; not too difficult to believe that even Hood might have started the rumor to excuse a bad tactical decision.
The site doesn't source it, but maybe it's worth looking into some more. If I find time today (not likely, but who knows?) I'll see what I can find.
