on top of the portal/transfer anytime you want BS, a lot can happen over the next (almost) year and a half.
maybe i'm wrong but i think maybe the worst detail about the BS is:
remember how long it took and how seldom it happened to develop OLs, and maybe to a lesser extent, DLs into champion level groups? not saying it can't or won't ever happen again but we've rarely had dominant key groups in recent times and that was before these negative major changes in CFB that make it even more difficult to develop chemistry and detailed playbooks.
