To be honest, I don't watch much college football. I watch the Terps whenever I can, and will watch just about any football if it's on, but I'm not a real fan. But, I hear that great college football teams don't rebuild, they reload. What that means is, when all the star talent heads to the NFL, instead of having to rebuild from scratch which takes a few years, the great teams reload with the talent they already have on the team. Most colleges teams don't have that ability, but some do. USC & Ohio State come to mind (remember: my knowledge of college football is not so great).
Churches should learn to reload rather than rebuild as well. In football they're reloading with talent. The church should be reloading with new talent and leadership. It's critical for a college football team to be able to reload because they're talent leaves in 3-4 years whereas most churches can sit content because people aren't going anywhere. But, healthy things reproduce and healthy churches should reproduce as well. Reproduce talent, leaders, campuses and churches.
If a church is like a great college football team, the talent and leaders are there waiting to be called on. They're there because the church is intentional about getting new people involved and developing leaders. They're there because the church creates space for them to serve and takes risks on people. They get opportunities to grow and take on more responsibility because the church is growing and/or sending people out to start new churches and campuses.
If a church is like a bad college football team then nobody is going anywhere and there probably isn't much to reload with anyway. So, if for some reason they need more people to step up, they have to rebuild. That takes time and limits how quickly a church can respond to an opportunity.
Hopefully more and more churches will be able to reload, and not rebuild.
