Anyone who thought he was a franchise player, overrated him. Anyone who thought that he was the player to build a team around, overrated him. I have read plenty of those opinions on both the Deck and the ORG.
Clearly, that does not refer to you, or anyone else who felt that he needed better hitters around him. By definition, a franchise player is one who doesn't need other great hitters around him. He is the anchor and you build the team around him with role players.
A good analogy is movie stars. Dunn is like a great supporting actor, one who could win awards as a supporting actor, but who should not be the lead.
He is Robert Duvall, Greg Kinnear or Gene Hackman, not Robert DeNiro, George Clooney or Brad Pitt. He can make a movie better by being in it, but he can't carry it by himself.
There are not a lot of franchise players, maybe 15-20 in the league, so it is no big critique of Dunn that he is not one of them. But there are Reds fans who thought he was one. They overrated him.
