Fair enough; Kohou has some a lot of potential. However, I'm an idealist trying to survive in a realist world. I believe things should be fair, but it's impossible. IMO, something is wrong with the entire system when Pass Interference is called on one DB, but when another DB does the EXACT same thing, it's not called... there needs to be consistency. Holding by o-linemen is another big issue because it happens every play but isn't always called. Either call every hold or make it legal; otherwise, it's not fair. When Brady was a Patriot, we Dolphins fans know for a fact that his o-line got away with a lot of holding because the League wanted to protect its "Golden Boy", and that was blatant bias in favor of New England.
On one hand, I really wish that they'd use modern technology to see the whole field and call EVERY penalty. I don't care if it makes the game longer, it goes by too fast as it is, and I'd rather that the game be 100% fair. These guys get a LOT of money to play a game, and if it takes an extra hour to make the game fair, what's the problem? They're still only playing for 60 minutes!
On the other hand, since the Officials are human (imperfect, and possibly biased) and the League refuses to cut into its profits to use technology to ensure that the game is fair, let's just do away with rules that are never enforced fairly. Make holding by linemen legal; do whatever you want, as long as you don't take the guy to the ground. I'm actually surprised that they haven't officially done this already, as they've been doing it unofficially for years to protect certain QBs. In the old days, defenders were draped all over WRs as they ran their routes, so let them fight it out again.
Unfortunately (for me), although football is a sport and by definition should be played with fairness and good sportsmanship in mind, the NFL is in the Entertainment business and doesn't care about fairness, just profits.
