I just don't agree with that at all. The point is to have three go to guys, and two solid guys who you can also count on to score at all times. Playing against a triangle with two obvious guys scoring at all times, is very easy to defend if you have talent close to the team you are playing against. You can look at real life situations where this is clearly seen, all the way up to the Pro level. Will you win games relying on one to two players? Sure, but in my opinion against the top teams, you must have 6-8 guys who you can count to share the scoring to run an elite triangle offense.
