He starts biting my hand really hard and if I try stay still and ignore him it doesn't affect him, he keeps biting, if I move he still bites, jumps and at that point I grab him by his collar and sit him down while he tries to bite my arm. it usually doesn't work and I need find a distraction. it happens a lot, it's getting really hard to not get frustrated. how can I train him to behave?

First off, I highly recommend a beginner training class with Nero, and also getting him into something fun and active such as agility or flyball, as Sheepdogs are extremely smart and extremely prone to boredom. Sometimes, having a focused training class or activity can help get out that energy and put your dog to work so they are less likely to become bored and destructive. As for nipping, there are a few things you can try out: Have a toy or bone handy that you can put in Nero's mouth when he gets excited to give him something to chew on and be mouthy with other than your hands/arms. If he picks up a toy on his own, be sure to give him lots of praise to help teach him this is a good thing. If walking away or yelping doesn't help, teaching him something such as "settle" can help him to focus on calming down and relaxing instead of ramping up the behavior with more excitement. Grabbing his collar and holding him down is likely just exciting him more, but focusing on training such as sit, down, settle, etc can divert his focus into something productive instead. Practice "airplaning" treats. This involves having Nero sit and slowly bringing a treat down to him. If he jumps up or gets excited, you have him sit again and start over. Once he can focus on staying still, he gets the treat. This can help teach some impulse control and reduce excitement behavior. Give him a job! Redirect his attention by telling him to go find a specific toy or bone. This can help him get out that excited energy and focus on chewing on the toy, instead of jumping all over you.
