Someone said thorws don't work well against a guy who jabs a lot. Not true if you use good punching combos to set up a clinch and then throw, works fine. Trips are really useful on the street and greco or judo throws. Leg attacks can work ok but I'm not a fan of going close to the ground on the street and you might end up breaking your knee.
