It would be nice if the apparent embarassment reflected in some kind of change on the ice.
Moffie has had an A on his sweater, and, in theory, should be earning that as well as the scholarship he's got. You should be asking him the tough questions- such as- "why do YOU continue to pass so badly in our defensive zone? someone who is as experienced and has an A on your sweater"
These guys should not be getting nurf toss kind of questions, but deep ones. Being kind doesn't seem to work.
How about "you look embarrassed- why does this not translate into actual changes and development on the ice?" That seems fair.
What's funny is that you've and others reported that they know something is wrong, but not what it is- yet that has not changed ANY play on the ice. In some ways, it's regressed.
