Bob Valvano (brother of the late Jim Valvano) on his nightly radio show once went through a synopsis on why he believed players were having so many mental breakdowns in pro sports today, it went something like this:
When we were kids, we gathered together, decided what game we would play (football, baseball, basketball), we would set the field up for play, we would set the rules, then divide up into teams. During the games, we refereed ourselves, and sometimes if it got out of hand it may have come to blows. After the fight was over, we moved on. On the field we determined winners and losers and then we’d do it the next day.
Today, kids are chauffeured to games bu their moms in pre made leagues, with referees mediating conflicts, and trophies for the winners and even the losers.
One problem with this is an elite player is sheltered from the stress of conflict, travel, team building, etc which at their younger ages may be shielded, but when these players reach elite college level or pro level the talent gap shrinks to where mental toughness becomes more of the edge between athletes and that’s where these coddled players tend to break.
