Here are good FaZe pickups
2. Xizt (very likely)
Any of these could be good, I really can't think of anyone else who would be good enough or even realistically be picked up.
You don't just tell a teammate to shut up in that way during a match because you are in a fight with him. Chris and someone else were arguing while NiKo was trying to call, that's why he startded yelling shut up
Yes you do because you need your team to fucking focus on your calls, it's all about being a professional at that moment. It was nothing personal.
Later a clip was released where ChrisJ was holding b main on cache with an awp, and Niko asked if Chris was ready. I won't spoil the end but it shows that they are not mad or aggressive to eachother at all.
