Agreed, Parayko wouldn't be a poor selection; I wouldn't have him on my team (he'd be just outside), but certainly justifiable even if his own GM selected him for the reasons you mentioned.
Armstrong has mentioned previously that he would like the management team to "keep on eye on" Jordan Kyrou, which would be a huge concern obviously if that gets any traction. Kyrou is nowhere near good enough for our A team. Perron will likely get some consideration for a depth role, but I can't see how he surpasses the aging stars (Tavares, Stamkos) and all of the good young forwards that we have. If Perron ends up getting selected, I would definitely see that as nepotism on Armstrong's part. I don't think it will happen though.
