I don't think the Speed Force can go to just anyone. They need to be chosen or have access to the Velocity drug.

Also, how are we sure Griffin Grey is dead? He could've just exerted himself to the point of incapacitation and then revert back to his young self as a consequence. If he is deceased, he at least got to regress back to his actual age.
