Just had this discussion with somebody on FB. I wouldn't be opposed the Steelers bringing him on a tryout. If you've seen the Steelers cap situation and the free agent pool for punters, more than likely it will result in one of two things: bringing in somebody who has been on the streets for a year (i.e. Kluwe) or drafting a punter. The only players available in free agency are Pat McAfee (makes $3m), Moorman (who punted worse than McBriar), the punter from the Eagles that had worse numbers than Kluwe's 2012 season, and the previously mentioned McBriar that finished 32nd in punting average.
But as far as whether what Kluwe said is true or not, I don't know. Like most of these stories that surface, I think the truth is somewhere in the middle. Let me preface this by saying I was a fan of the guy. Seemed like a good guy on twitter who didn't seem like the typical football player, he put up good numbers for most of his career in MIN, but was very vocal about his beliefs. However, there are ways of showing your beliefs and then there is Kluwe's way. I don't know whether he was cut or not because he had a strong belief in helping the LGBT community, but I'm sure making mention that "being gay doesn't turn you into a lustful (rooster)-monster" isn't the message the Vikings want associated with their team. Even the Ray Guy HOF incident, which although harmless to me, might be looked as insubordination within the team. He was told to remove the tape covering the HOF patch, and Kluwe said no; that the fine will be worth it.
But what's also is left out that he was a punter in his 30s with a high salary ($1.6m in 2012) that was in the lower tier of NFL punters statistically and coming off of knee surgery. 22nd in average, 31st in punts inside the 20, T-30 for touchbacks. The Vikings basically went out and found a punter that was less outspoken that could put up the same numbers for 1/4 the salary.
