I'm not sure it's a good idea for Nick Foles to be tooting Riley Cooper's horn so fresh after all that racial drama. We want Nick Foles to actually get the starting job. If he's perceived as being too complimentary towards Cooper I feel like that could hurt his chances with a team that generally seems bound and determined to play blacks at quarterback. The last thing he needs is to give anyone even the slightest reason to suspect that he's raycissssss. He should have simply continued to throw to Cooper during the games but save his praise of Cooper until after he is entrenched as starting QB.
Anyway, I too have noticed that whites are always boring and blacks are always exciting (according to the media anyway) and I'm damn tired of it. Boring is subjective. If it's a team I care about, I want their QB to be a primarily pocket passer type who is consistent, accurate, smart, a quick thinker, good leader, humble, and able to scramble effectively on occasion when he absolutely needs to, because those are the kinds of quarterbacks who win games and winning is exciting. Sometimes I think some football fans would rather lose by a close margin with an "exciting" QB than win by any margin with a "boring" QB.
The notion that pocket passers QBs (usually white) are somehow too "boring" may also be due in part to the fact that society is now far more impatient than it was 15 years ago due to the internet and technology being able to give us everything we want right when we want. Subtlety is under-appreciated these days. Think about all the most popular TV shows. The amount of action in TV shows these days has increased, as has the amount of violence. Jokes are more frequent and heavy-handed in our comedies. The news is more sensational as if they're trying to bait people into having feelings about it rather than just informing us. Look at shows like The Blacklist or Breaking Bad, action-packed, violent shows that move at a breakneck pace. Shows like that would have been too overwhelming 20 years ago, now that's what all shows what to be. Nobody's happy with just being consistently good, you have to always be upping the ante and keep topping yourself over and over.
I think that's why people have changed what they want out of their football teams. They aren't happy with QBs who just win games. They want their QB to be the biggest fastest dude out there and for every play to look like a highlight reel clip, winning be-damned. Bonus points if he has off the field problems or routinely says stupid things to give them something to talk about.
