Charley Rosen, Jackson’s confidant/biographer and his former Albany Patroons assistant, has appeared in two episodes. He’s still worried Jackson’s failed 3 ½-year run as Knicks president has hurt his perception in New York. Rosen said Jackson should never have come out of retirement and taken the position in March 2014. “I told him not to take it because it’s crazy there,’’ Rosen said. “Jeanie [Buss] told him not to take it. If he came there, it would end their relationship 3,000 miles away.”
