Though lighting for sure and as others have pointed out, these are over exposed. Does the D3 have the capability of shooting at ISO 100 vs 200? Noticed these were at 200. Other comments:
#2 - OOF
#3 - still a tad OOF, were you focused on the center of the blue jersey player? Little contrast can cause this.
#4 - nice and low, exposure a bit better on this one. Action I would call medium vs peak. What did the next frame look like?
#5 - not certain what the intent for this one was
#6 - very good but the exposure kills it, try correcting in PP
#7 - good action
You might want to consider using F/4, which still does a great job at blurring the BGs and provides a bit more DOF, especially where there is ample lighting.
