Because of the highly competitive D1 atmosphere, most D1 programs plan on using their kids, even the freshmen. The roles may be minor, but few schools can afford to "season" a kid on scholarship -- he is "expensive". A few other things to consider....
Our son was looking for the "total college experience" and I don't use that expression to minimize or criticize the JUCO. He wanted to go to the football games and chase sorority girls and stuff....and establish a 4-5 year life there. It was important for him to create a new home. That can happen at a 2-year school too, but the shorter time frame contributes to a "short-time" feel.
Some JUCO (notice "SOME" -- when using this term, I think it's difficult to argue the point) have a bit of a carefree attitude towards the use of "suppliments" (is that an ok word to use here?). There is at least one JUCO (a neighboring state, not Texas) where the coaches INSIST on a steroid regiment....even in today's world. My source is reliable.
I won't get into the discussion about quality of education, etc. The cost issue is definitely a HUGE plus for the JUCO option.
All in all, I think it depends on the kid.
