I think it's ludicrous that we haven't issued #21 for 17 years.
Keffer McGee, while we all mourn his loss, wasn't the first person to ever wear #21, and he shouldn't be the last. I've also always thought it odd that people get up in arms about #21 being reissued, while at the same time #97 has been reissued numerous times since Rodney Stowers died in 1991.
And for the record, I hope #36 is reissued whenever someone wants to have it.
Those numbers aren't final resting places, they should be legacies that other young men have the opportunity to live up to, just like any other number on the roster.
