There are 3 pillars to having a successful club:
If you have a great uniform supplier, but little or no community engagement then your players may look good, but your club will ulitmately be poor.
If you have great engagement with your community and sponsors, but a uniform supplier unwilling to add sponsor logos on jerseys, you may be well funded but will lack image and continued sponsorship.
Worst of all is if you have a lousy uniform supplier and little or no community engagement.
As you can see, if any of these are not working well, then the success for your club will be limited.
