It's the classic question of do you prefer a reflective poll or a predictive one. Some people attempt to rank the teams according to where they will finish, others reward past performance. Many try to blend the two, but the implementation is always a point of contention.
I prefer ignoring ranking until about week 5, and then leaning more towards reactive polls rather than predictive. No point in playing the games with predictive polls not penalizing losses.
I think within week 1, keeping TCU and LSU ranked are fine, but if they continue to underperform or other teams overperform, inertia shouldn't keep them in.
Is there a specific way to join the poll?
