I believe we are still at 52. If they wanted to bring Fournette up, they can always move Ty Johnson back to PS. So they have lots of flexibility if they want to bring in another player.
I just googled it. Ottawa was named initially in tribute to Teddy Roosevelt's Rough Riders. They changed their name to Red Blacks which were the colors of the Rough Rider uniform.
Still...who won the game?
But rough riders were members of their mounted police. I think there is another Canadian team still using that name. I'm wondering what a redblack is. Is that a reference to a uniform?
