Pretty funny that someone submitted pretty much their old logo. Twice actually.
The last 3 logo's are ok. The last one is indeed the best of those 3, although it looks kinda arena-football-like.
I do think that the last thing that needed overhauling was their logo. It looked quite cool actually. Even if they do want to change it, why not go the the '60-'70 logo. That one is still pretty cool.
