I like simple and easy nicknames. 
Still think King of the North and the Finnisher are the best two for Lauri. 
Vando is already established - although V8 is pretty good branding. 
Sex Machine - needs no explanation (I hope). 
Kelly “Punchable” Olynyk - we all know it’s true no matter how well he’s playing right now. 
Kessler looks like a “Babyface” to me. 
Italian Stallion for Fontecchio might be boring, but it still seems to work/fit pretty well. 
THT is fine. Although, I did get a solid laugh out if Talen “Mother” Horton-Tucker.
