Super Introvert? Heheh, you don't sound like one to me but I agree, Hive is a super cool place that accommodates us all!
A coach who transformed your team to victory and great heights will surely be held in high esteem. Shows he was dedicated to your team and gave his best.
I like such people, they motivate me to win. Is he still into coaching? I'm sure he treasures every team he had positively influenced.
