I see Braun as a HOFer, barring an unforseen injury, and, to be honest, I can't understand the skepticism. Braun's 2011 season, in which he won the NL MVP, was a season not out of context with the rest of his career. Braun posted his best season in 2011, and it was his best by a significant amount, but it was not a fluke season by any means. Indeed, given Braun's age in 2011 (27), it is well within what one would project for Braun; he's taken his career to a new level that is reasonable for him to approach again and again over the next 4-5 years.
Braun is doing what HOFers who play LF do. He's won awards (2007 NL ROY, 2011 NL MVP). He's been on the All-Star team the last 4 years in a row. His BA is .312, and he averages over 30 HRs and over 100 RBIs per year, so he's not offensively overmatched for his position. He's the best player on a team that makes the postseason. These are the sort of things HOF left fielders do, and Braun does them. His OWP this year was .799; that's outstanding. His OWP for his career is .712, and that's HOF norm for a player at the left end of the defensive spectrum.
I also can't agree that Braun "didn't deserve the MVP award" in 2011. A case can be made for Matt Kemp being more deserving if you factor in his Gold Glove for CF, but Braun was the superior offensive player to Kemp; indeed, he posted the best offensive season of any player in the NL if you go by OWP. I can understand a vote for Kemp for MVP, but I can also understand not voting for Kemp in rememberance of his poor attitude in 2010 that cost the Dodgers. Braun may or may not have been the best player in the NL, but a strong case can be made that he was, and it's a matter of there being more than one deserving candidate, but only one award.
"I do not care if half the league strikes. Those who do it will encounter quick retribution. All will be suspended and I don't care if it wrecks the National League for five years. This is the United States of America and one citizen has as much right to play as another. The National League will go down the line with Robinson whatever the consequences. You will find if you go through with your intention that you have been guilty of complete madness."
NL President Ford Frick, 1947
