The OP is finishing his second JUCO year---this says he is draft eligible---what are the possibilities of being drafted this summer?
For the me fact that at the top D-2 he will play regularly says go there IF NOT DRAFTED THIS SUMMER
Additionally you have the $$$ factor--what money are you receiving at the SEC school? You know what you have at the D-2 school.
There is a lot to consider here--let us not make this so simple
