Players want to participate. They may be talented and they may be very willing to make some sacrifices, but they are not necessarily talented or all that willing to make the necessary sacrifices. They may play to be part of something. They may play because their friends do or parents pressure them. However, while not necessarily lacking talent, they typically lack commitment.
Winners win because they have participants who are talented.
The capability of a team that has enough talented participants will certainly produce winning records. However, talent and participation are not enough to win championships. Further, champions step up to fulfill their responsibilities by being ready and able to perform each and every day practice or games. A team consisting of champions has a compliment of players who can fulfill their respective rolls they get the job done. Players today play multiple sports and participate in all kinds of productive and meaningful activities.
