Yeah same. I am a big Rhule fan but the single digit thing is a swing and a miss for me. It just creates awkwardness. Player numbers are supposed to be "permanent," at the very least throughout a season, but also usually throughout a career. Imagine Ahman Green being #30 in 1995 and 1996 and then suddenly he's #2 in 1997? Suh being #93 and then oh, now he's #6?
It just rubs me the wrong way from a macro view like that, but then also there are situations like last year when Jimari Butler was #1 and then suddenly he didn't want to be anymore and went back to #10, and Vincent Shavers was #1... ? Did that mean Shavers took over the spot as one of the Tough Guys and Butler was demoted? Shavers may well have deserved it, but using uniform numbers for this type of "honor" just doesn't work for me. It's even more awkward than giving and taking away Blackshirts in the Bo years.
My suggestion which obviously carries zero weight, would be to use the early Frost thing of putting guys' area codes on their helmet, except it's just for the 10 toughest guys or whatever. Less distracting, less awkward, still a way to honor those guys by letting some of their individuality and hometown pride shine through.
I also just don't agree with the premise that single digit numbers are inherently cooler or "tougher" than double digits. haha
