The NCAA doesn't limit calamari (awesome spell check, Calipari) from recruiting new guys to replace old ones. Now if they said you have to wait April to start recruiting then that would be a huge issue/hurdle for the UKs, KUs, UCLAs, and etc... of college basketball.
now I know mike will say u can recruit during 1st session but the att pts and recruiting dollars are not there when they are needed. the att pts are at best 1/3 of what a normal schollie is and in more cases that's not more like 1/6 as effective with a fair share of recruitable DI reserve type players off the board in the the 1st 2 or 3 cycles.
