Welcome to Allen Alex!
Recruiting lasts 5 days. Then you have 2 days for exhibition games. Then the regular season starts. Spend those two days during exhibition to set up your practice plan, offensive distribution and team gameplan.
Looks like you're losing 3 seniors and 2 walk ons so you'll be recruiting with money for 5 guys. This is awesome since it'll help you rebuild faster. But that also means you need to do well in recruiting or else you could set yourself back a few seasons. Along with the article that darnoc posted, also read this

It gives you more details on how recruiting actually works along with what potential is, how it is important and how to scout (mostly with FSS).
Keep posting questions on the forums when it comes up and feel free to site mail me.
