Is cloning legal in the CBA? Do both count against the cap?
There is nothing in the CBA against cloning, but the question is if the team retains rights to his DNA since that is not part of the SPC. Also current cloning technology is limited to zygote, so we'd be waiting 18 years (plus 9 months of incubation) before the player is ready.
In any case, I'd clone DBoss instead. The roster would consist of 23 DBosses, with the fastest goalies in NHL history.

DBoss (the original one, aka DNA donor)
Note: Half the Dylans will be raised left handed, and the other half right handed. It is possible to raise a child using the weak hand, everyone writes with their right hand in Japan.
