Club Basketball improved

[TallDude]

It's been a while since my last post, but I've still been busy shooting my son's club basketball team. I have to say, I'm loving LED gym lights. Pretty much all the gyms have converted to them and it's given me some elbow room. Prior to that, I was stuck in the f2.8 shallows. 250 to 500 tops and please "No" 3200. NR city I have a Canon T2i with a Sigma 18-50mm 2.8. Lately because of the LED's I've been able shoot f4 , 1000, and stay at 1600. I'll shoot a little under in RAW and even better.
So now I'm trying to refine my focus. I'm using single center, but still not feeling that is always the best? I'm also framing better and taking fewer, more select shots. All this just in time for my son's club years to come to an end. Glad and sad. On to High School where I can still keep shooting.

Here are a few of my more recent shots. Any advice or critique is always welcome.
