I'm quite surprised that this is the only sport-related bench in this challenge. The idea of being benched was the first thing to come to my mind when this challenge was announced, though I didn't enter. I think you've captured the idea of "losing" very well here with the cheerleaders standing in the background, but I'm less fond of the processing. I don't mind the selective de-saturation as much as I usually do (perhaps because it's subtle, but I'm not fond of the diffuse glow or whatever is giving that effect.
Great emotion and composition, just ease up a bit on the processing and let the player's emotion draw attention to itself. In sports, outside of advertising, we rarely see heavily processed images. In this case, just a little bit of editing can go a long way.
Though I don't think the number is right for it, it gives me the feel he's a kicker and he just missed a crucial field goal. I do rather like the desat on this.
