I'm probably cynical, but I think MD schools emphasize numbers way too much and only give some weight to good ECs. Clearly, good numbers and good ECs = success for MD schools, but given the choices between good numbers and average ECs vs average numbers and good ECs, I think schools would pick good numbers over good ECs.
This isn't an absolute rule or anything, since there are applicants who have so strong ECs and application profile that their ECs can actually compensate for below average stats (there were a few people getting into top schools like JHU despite having a 3.7/511 and that's largely due to their super strong activities). These cases are rare though but something to keep in mind.
DO schools are a best bet for applicants with average stats if they want to get accepted somewhere. Unfortunately, and while SDN isn't representative of the overall applicant pool, MD admissions seems a bit brutal against applicants with average stats and ECs that applying to some DO schools is a nice "safety net" to get accepted.
