That is quite an area for the OC to cover. Florida, if you truly want to mine it for the best talent, requires one coach to monitor it at the very least. You need to have relationships with coaches (meaning, if you gave McDonald that big of an area, he would need to build personal relationships with 100+ coaches). While he already has these relationships in Florida, I haven't seen anything to relay he has these connections (at least in sheer #'s) in the other states discussed.
I rather he spend his time breaking down defensive film and devising an offensive game plan then spending time on the phone/emailing/reviewing video during the season with coaches.
