The NFL doesn't hype individual players? Please share whatever it is you're smoking. The NFL is popular because the salary cap makes almost every team viable (increased parity) and because of that dirty little secret centered in the Nevada desert that the league doesn't like to talk about. The mandatory mid-week injury report is for the good of the game, right? It has nothing to do with gambling...
The job of the networks is not to "grow the sport." The job of the networks is to put on programming that will draw the most viewers. There are only a handful of national teams that will brings the ratings they seek. Sorry. And yes, in the past most news was carried by newspapers or the radio. Welcome to the 21st Century where those things have been replaced by satellite TV and the Internet. Nice of you to have noticed.
It sounds like the problem most of you have is with the networks, not the Red Sox nor their fan base. Maybe try directing your displeasure correctly and not aim it at the team or the fans. If it bothers you so much that the same few teams land on national broadcasts that you don't want to watch anymore, that's a shame, but you can always buy an MLB.tv or Extra Innings package so you can watch that exciting Padres-Astros matchup.
