OP Stated:
The 7 year program at NSU is not binding and I am able to apply to other medical schools if I wish.
By accepting entrance into the program he isn't shutting himself off to the MD pathway, should he choose to pursue that path later down the line...
In terms of matching for MD vs DO, I would like to argue that by time OP is applying for the match there probably won't be any significant differences in terms of matching most specialities - Consider that we are talking at least 7 years down the line. With all these DOs infiltrating ACGME residencies pre-merger, I am certainly interested to see what happens post-merger. I wouldn't be surprised if DOs overtake MDs in the match by the time 7 years has passed.
We DOs are sneaky
