Is auburn a one year wonder?

I know that they have been really good before, so please don't use that reason, this is not a thread about the history of Auburn, this is about the future.
My reasoning for asking this is based in some logic so please hear me out.
1. Cam Newton - they will more than likely lose him this year to the NFL. I can be a man and admit that he is one of the best college football players I have seen. He is a one-man army and might be one of the most impossible replacements. Meaning that Auburn might not ever get a guy like that in the near future.
2. Gus Malzahn - almost everyone knows that he is a head coaching job away from being gone. With all the rumors about either Petrino or Mullen taking the Florida job, you have to assume that Malzahn would be crazy not to take either of those teams vacant jobs. With him gone, I don't look for Auburn to replace him with someone of teh same calibur.
3. Camgate - I don't pretend to know how that will end, but if it ends badly, as in postseason bans and scholarship losses, this might put them back a long time.
4. O-Line - Auburn is losing 4 of 5 O-linemen this year. That right there is enough to put them back at least 2 years. But regardless, it is very hard to replace that many people, and remember that it is more than likely that they will also be losing Mr. All-American Cam Newton as well.
5. Revenge factor - it happens every year, but if you are on top, you get everyone's best game. With all the things I have just mentioned, this can't be a good thing.
I know this is long, but I really do wonder if all of the things I just mentioned might have the possibility of causing Auburn to not get back to this level of play for a long time. maybe I am just wishful thinking because I can't stand Auburn, but you have to wonder if all of these things will cause them to slip into a Miami slide into not being relevant. Your thoughts?
