Zaza may not be a good scorer but I like him because he is a tough player, and brings intensity to this team (which we lack a lot of at times.) He is not scared to go after the ball on the offensive rebounding side, not to mention the guy throws his body around all the time. Zaza to me plays a lot more physical ball than Horford does.
That being said, it will be very interesting to say the least to see where and who ends up on this team next season.
