In the midst of all of the hullabalu over Gilles, Shawn, and Melissa last season, I spent considerable time on the ABC board (as well as on here). You had better believe that there are literally hundreds over there who are die hard DWTS fans for their favorite PRO first ( and then whoever the star is that is partnered with the pro. They have huge threads going for that pro, and they fight each other bitterly over why their pro is the best and should win ( everytime).
Do I think others should get a chance to win? Heck yes! If that means that young Mark or Derek gets a 50, 60, or 70 year old woman, than so be it. It would be much more of a challenge to take one of those ladies to the finals than a model or an Olympic champion. Likewise, when (if) Julianne comes back, it will be a challenge to her as well if she is given a much older man than Apolo or Helios(?) to try to take to the finals.
As far as this season goes, Derek again has the young woman with a lot of looks and potential; however, she does have it, and if they win, then they win. At least Joanna isn't a professional dancer, and she has shown much improvement from the beginning.
