Yes, I was just about to post similar, RJA.

Much of the improvement in mindset has to come from Oli himself, however much others could help. The problem today appears to have been Oli's reaction to the loss of that game at 5-2*. It should not have inordinately effected him, given his previous security on serve, but unfortunately with Oli it appears it did, and with Oli that is I am afraid no huge surprise.

I do accept that players mature in different ways at different paces and do think some worry too much about direct peer rankings comparisons. Oli remains a good prospect, and whether that's possible / likely top 50, 100 or whatever is open to individual judgement. And, of course, a good coaching / mentoring setup would be very helpful.

But he should be sorting some of these issues out himself !!

Not wishing to re-open the can of worms re US college tennis, or even really the French/German system, but in my view Oliver would have benefited greatly (and would still benefit?) from playing a whole heap of team tennis.

There are two main benefits from growing up playing a lot of team tennis (and preferably mixed ages i.e. adults, veterans and juniors) :

1. When you play a lot of team tennis, you learn how to win a match, how to close it out, how not to choke and dump it. You play in front of your team-mates, the coach, team captain, club president, lots of supporters (club members or students) and you can't, simply can't, have a hissy fit/collapse and throw away matches. Obviously someone loses but there's a pressure and a focus that means you learn how to eke out victories.

2. You get non-stop match coaching. There's no point really Oli having a coach who sends him out of court feeling great if, two hours later, he;s in his own lonely bubble, feeling grim and blowing up. In a team match, at each change of ends, the captain will advise, encourage and/or give you a right rollockin, depending what's needed. It's a great learning tool.

I believe that Oliver will do well, he's too good a tennis player (I hope) not to. But there's a slight prima donna side that team tennis would have knocked out of him.
