I think Musselman had/has a newsletter that a lot of coaches subscribe to, and has built a following among coaches who like his thoughts on leadership. He has been tweeting stuff like that since long before he was at Arkansas. In fact, when I heard he might be hired, that was the first type of tweet I saw when I looked him up.
It reminds me a little of Mike Neighbors, who built a big following with his newsletter before he came to Arkansas.
thanks Navy I don’t really see anything in there that is not the truth,being a coach myself I see it as his way of constantly reminding of things like that that will make or break a team,BTW I loved that little video I saw a team working exremely hard! very refreshing.
