I think the days of the huge power forward are over.
The body types of the Plugger, Gherig and to some degree Neitz, i beleive, are sought out less and less.
The way to go is the Franklin, Mooney and J. Brown, strong and tall but fast off the mark.
Miller has the right body type, is not a turtle and has the skill (when he feels like it.)
What is it that is stopping him from becomming one of the new day forwards?
Y_M, you may answer if you are not just wanting to bag him
