No doubt there is some subjectivity involved; would you have them just award it to the back with the most yards? If so, how should we distinguish between passing yards and rushing yards? Should we include return yards? Since I am not on the panel that picks the finalists, I cannot tell you what criteria they used. I can tell you that perhaps one such criteria may have been the level of competition. It looks like 3 of the 4 nominees for Mr. Football in the D1-A back category come from the west. Based upon the first round of the playoffs, the west seems to be the far superior to the division in which DCA plays. In fact, it appears that the only team that DCA played that is still alive in the D2-A playoffs was Webb, which administered a 41-17 beatdown in that game. The other nominee is from Webb, which also played first round winner BGA, Alcoa and Oak Ridge. No offense meant to DCA, 'cause they played the teams in front of them and have had a great year (and again, Walker is an excellent back), but it just might be a wee bit tougher to put up those kind of stats against some legitimate competition. You are certainly entitled to your opinion, but I will accept the opinion of those handing out the trophies over that of some anonymous homer on a message board.
And yeah, despite your protestations to the contrary, you are clearly implying that your candidate is more deserving than at least one of the semi-finalists, so you are showing disrespect to those nominated.
Congrats to all of the nominees.
