Caveat: Due respect to those that have played and/or coached at a level higher than little league, I have not. How a full time player thinks is unfamiliar to me, but I'd like to believe it is not significantly different than an average 20-30 year old at work.
Look, I love to watch a pep rally and a fired up speaker as much as the next guy, but I have little confidence in its effectiveness short of a short term adrenalin rush for the audience. The proverbial kick in the ass would seem to only serve the purpose of getting an individual to focus on the immediate task at hand. To suggest that is necessary for this club, then, is to say that a professional hitter is standing in a batters box watching 90+ mph fastballs and is somehow letting his thoughts wander elsewhere and/or not "want enough" to get on base. Or, that a pitcher center stage in front of thousands of spectators and the glare of a batter, catcher and ump is anything but 100% attempting to throw the best pitch he can, every time necessary. This seems completely implausible to me, at least at this stage during the season. (see again, caveat)
Rather, wouldn’t it be more realistic to believe that the outcome of a game (and more specifically, the outcome of each individual action that occurs during the game for each player) is instead the result of numerous factors such as natural ability, training, mechanics, preparation, fatigue, strategy, random decisions, game situations, weather, field conditions and an enormous thing called chance that are not at all impacted by the words of a motivational speaker?
This reeks of "The Secret" philosophy of merely willing something to happen to you as an effective life strategy. 100% Bullshit consumed in large quantities by the simple minded who need an easy answer for everything.
A parallel in my own life would be my golf game. I am fully committed to breaking 80 (haven’t yet) and absolutely beat myself up over doing it. Within a two week span, I have played the same course at 82 and 102. I can assure you that the difference is not desire, will or focus, but a myriad of factors such as those listed above. To achieve my goal I must always be able to identify the weakness de jour and focus on solutions for it. Having Bagwell call me a panty waste for missing an easy putt will likely do nothing to improve my game at this point.
The problems between the lines are real, and of legitimate concern, no doubt. I think time is better spent identifying the individual areas of concern for each player and focusing training/practice efforts there. Suggesting that the team just doesn’t want it enough is a weak out. That's too easy an answer.
