Yes, Dexter can win. I'm not sure he will, but I think he's a lock for top 4 unless he hits a major snag on the way to the O.
In no particular order, here is my top 10.
The top 4 are probably locks for the top 4 spots. 5-10 could be really interesting. Ian Valliere
could be the real sleeper. He seems to have the total package of size, shape and density.
If he can figure out how to dial it in for the big day, he can crack the top 5.
