If you look at 5-6 nominees and truly believe that they deserve the award, you may vote for them.
I also know that there are many games each week that are unevenly matched. If the player you nominated is going up against a team that you dominated, just briefly mention so. so yes, I think it is a good idea to submit the box score of the game so the voters can get an idea.
Regardless of the competition I would say that 17 receptions and 13 of those going for TD's is pretty impressive. Just imagine what he could have done with the one he dropped.
