I don't think it's nearly the egregious decision some are claiming.
Bottom line, he decided that having the ability to set his D and instruct his players properly, so that something insane doesn't happen, was worth Memphis also getting to set something up.
Because it's such a difficult circumstance for Memphis, I understand that thinking. A player doing something illogical, or the defense getting mixed up, or whatever, is one of the few things that could allow them a successful play there. He felt that calling a TO would avoid anything like that.
You can have the offense with no chance to set up and in a mad scramble, but he's responsible for HIS team, and he felt avoiding anything dumb or a mistake on D in that situation was worth it.
Not sure I disagree that the TO is the lesser of 2 choices, but I definitely ser a coach's point of view in calling one there.
