Michael Blackson says Washington should go easy on Montae Nicholson -- because with all the issues involving NFL players these days, it coulda been way worse.
We broke the story ... the Redskins safety was caught on video KOing a man in a street fight with a devastating left-handed power shot. Nicholson and another woman were later arrested.
Some people say Nicholson took things too far -- and should have walked away from the fight before knocking his opponent out cold.
Enter Blackson -- a man never short on opinions.
