A coach praising his/her player(s) in lofty terms is leadership; Let's the player know that he/she has faith in them.
When Coach Auriemma calls Rebecca Lobo the worst post player in the country, or berates a player with a comment like, "You got exactly one more rebound that a dead person," that is motivation.
A coach of a lower echelon team going up against UConn is not going to tell the team that they have no chance to win. They will scout, game plan, prepare, and practice with an eye toward a monumental upset.
