There have been 207 hits in Games 1 and 2, with the Lightning holding a 107-100 advantage.
The series figures to remain physical, so the first team to give an inch in this area could find itself getting knocked off the puck enough to lead to chances the other way.
"It's been physical and guys are doing everything they can to win," Tampa Bay forward Tyler Johnson said Wednesday. "Dallas is a bigger team, strong, and they play good defensively, structured. We do too. When you get two teams like that, it's going to be a hard-fought battle. Both teams, going this far, you're so close yet you're still far away and you're literally doing everything right now. We've had some good games so far and we're just trying to keep that compete up."
