I disagree with the "lots of issues with his theology" and quite frankly, we don't need a mega intellectual in the Chair either. He can always appoint someone more intellectual for the New Head of the CDF (or whatever it was called prior to Vatican II).
What we do need desperately is a man who can foster unity among Catholics. IMO, he is the man for that job. Some of those mega intellectuals are much less likely to be able to pull that off...mostly due to their pride.
CMRI has published twice an article entitled "The Salvation of those Outside the Church" ... a direct contradiction of EENS dogma, tantamount to printing an article "The Original Sin of Mary". They are also pro-NFP. Unless you properly understand the problem with EENS, there's no fixing the doctrinal problems that were at the root of the crisis. NFP has been a strong contributor to the erosion of Catholic doctrine regarding marriage and the marital state. Unfortunately, there are currently no Trad bishops who understand the problem with EENS (apart from Bishop Neal Webster, but he's well past his prime and also lacks sufficient training ... we saw how he messed up the consecration of Father Pfeiffer).
As for "unity among Catholics," having a Traditional Pope provides
ipso facto unity, so that'll be a non-issue. We only have divisions and disunity now precisely because there's no pope (or, for R&R, no Catholic pope).
