Ranking for McCombs

Has anyone NOT in the top 15% gotten admitted to McCombs? I want to apply there but my class rank is around 20%, but I have a near perfect score on my ACT and all around excellent extracurriculars/leadership positions/work experience;internships. Please let me know if my class ranking is going to drag me down in the admissions process. I’m working very hard on my essays so hopefully it would overshadow my rank? Not sure, apparently average rank at Mccombs is top 3-7%.
