What's your point. They were also way WAY less effective than the Redcoats, on a man-for-man basis.
The problem the British had was they simply could not effectively control 1.something-million restive Colonials across the ocean. They didn't have the power projection capabilities (and could not have afforded to do so if they did) to really maintain control of the colonies if the colonies refused to be ruled by them, particularly not with other enemies and rivals sticking their own oars into the water. The colonials, including the Continental Army, weren't all that well armed, they [i]certainly/i] weren't armed to the teeth.
