For me, there is no doubt about Walton (League MVP, Finals MVP), and Drexler (8x AS) deserving of retired jersey's as well as obviously NBA HOF. Great players while on the court. Coach Jack also made such an impact on the franchise for 10 yrs, that his #77 is warranted.
Beyond that, there are only a few worth considering for such an honor and it must include either EXCELLENT play and/or LONGEVITY. So, Petrie, Lucas, Paxson, Thompson, Kersey, Porter, Robinson, Wallace, Pippen, Sabonis, Roy, Aldridge, Lillard should be considered IMO.
Weinberg, Neal, Twardzik, Steele, Gross, Hollins, obviously were a nod to the contributions of the Championship season. Fine. Overkill? Yes.
In my own little world, I'd like to see Walton, Drexler, Lucas, Porter, Petrie, Roy, Aldridge and eventually Lillard jerseys reserved for no one else. That's my list.
Petrie and Roy had very very very similar careers. Short careers and little to none postseason success, but impactful players nonetheless. Aldridge is second on almost category ranking and Lillard is still doing his thing, but making a mark for best guard.
Fun to discuss this. I'm one of the guys who remember our teams clear back to the mid 70's and its fun to look back upon those years even just a quick visit.
