You'd be better off just tackling/charging the other guy rather than trying to block.
Yeah kneeing is easier to block, but you really have to be focused to block it since you are trying to move almost all your body at once in reaction to another person.

Blocking your neck when under a person is nigh impossible, and even if it's only a hyper-active 6 year old, if they get an elbow your neck it really hurts!

Hell go for the win, knee to the sternum and a blow to the neck simultaneously!
