90% of recruits that get offers from McNeese and UL are going to choose UL. Those that choose McNeese is due to purely geographical reasons, connection to school, or better chances of playing time early. Same goes in comparing UL to Ole Miss or Miss. St. for example. 90% of recruits are going to choose Ole Miss or Miss. St. over UL if they have offers from both. And that would not change if Cajuns happen to go to Ole Miss or Miss. St. and beat them (in a year when Ole Miss is not top 10 type team like this year).
I think it is much better to be playing for bowl game in present and (even if it is just a dream) possibilities of being nationally ranked in future, than on the other hand to be making playoffs in FCS year after year. I would rather go 6-6 and not get bowl invite than dominate FCS. Most teams that dominate FCS (such as Marshal for example) eventually move up to next level anyways and McNeese is hardly dominating FCS, just a winning program as it should be in a sea of smaller schools where for many football is not at all a priority in athletic department.
