To me it is obvious that they are retiring the numbers in chronological order. They started with Moore, Cournyer and Boom Boom. They all retired in the early to mid seventies. This year is Dryden and Savard. Both retired in late seventies, early eighties. Next up is undoubtedly Robinson & Gainey. I think there are 2 other numbers that will be retired before the Centennial season. I'm going to wager that it will be Roy and Lapointe. Let the speculation begin!!
