What I'm thinking is that the 2 that dressed for the game did not play significant minutes in their careers, and TB was not dressed and may have been disappointed at the way his BU career ended.
Probably not the reason, but just my wild guess.
Maybe Geno had asked them collectively if they wanted to do that or not.
I'd like to see from here on out the tradition to carry on, as next season, we will have a good group including DSE & WE who will be greatly missed.
Surprisingly, me and my buddies arrived 1/2 hr. before the game from Chicago! Once there, I was hoping to hear from the seniors. At least the game was a good one to watch.
