Does Kadri's Concussion Prove The Leafs Need Some Grit?

The Toronto Maple Leafs lost to the St. Louis Blues last night and also lost one of their key players. Forward Nazem Kadri left the game with a concussion and wasn't able to return, he'll be re-evaluated on Wednesday however it's expected he'll miss some time. The Leafs don't have any response physically to hits like that and it could be a dangerous thing come playoff time. Many have stated the Leafs' need to add more grit at the deadline and point to yesterday as just another piece of evidence. Sportsnet's Nick Kypreos pointed out on HockeyCentral at noon that Kadri is supposed to be the Leafs grittiest player and when teams can take a run at your grittiest player, it sends a message to the rest of the league. Do you think general manager Kyle Dubas needs to address it?
