I just think that it's sometimes hard to learn fundamentals watching professional sports players because they have talents that none of us will ever posess. And if they do give out "tips" it's usually very vanilla stuff that you can learn from a lot of people. The only way I think that it pays to watch good teams is if you are completely new to a sport, and since I don't know jack about soccer then ya, I would watch English Premier leagues if I was just getting into it.
For me, I learned everything by playing in high school, practicing, and listening to coaches. I grew up in Plano and played 2 years varsity at Plano Sr. High (didn't you say that's where you live?). I watched the NBA religiously in the early 2000's and learned relatively little compared to what I learned from my coaches.
The Lakers were a good team, but I didn't learn a lot just watching Shaq dunk on 7 footers and Kobe swishing contested shots.
The Kings were a fundamental team, but they just used a million variations of the backdoor cut.
The Spurs were good as well, but I knew I would never be as good as Tim Duncan.
