It was announced yesterday that Pittsburgh Steelers right tackle David DeCastro withdrew from the 2019 Pro Bowl, citing injury for the reason that he would not be attending. I think it’s safe to say that he would be healthy enough to play in a game that mattered, so unless he is scheduled for some type of offseason surgery we don’t know about, we can probably assume this isn’t about health.
I also don’t think it has much of anything to do with the prestige of the game, either. The Steelers had full attendance last year in large part because the whole coaching staff was there, but DeCastro has spoken previously of the importance of the honor of making the Pro Bowl, and my sense is that the mere number of Pro Bowls he has been to has simply gotten tiresome.
