Toronto is 4-for-24 on the power play in this series, but also has scored two shorthanded goals. Tampa Bay is 6-for-28 with the man advantage.
Lightning coach Jon Cooper believes his team has been better during 5-on-5 play and would like more game time played at even strength. But he's frustrated with the mental mistakes Tampa Bay has made that have led to penalties.
"It's the timing of our penalties, the type of penalties we're taking -- those are the ones that are biting us," Cooper said. "Too many men? We're better than that. A couple of pucks over the glass. Just freebies we're giving away at ill-advised times."
Toronto scored a power-play goal and two 4-on-4 goals in Game 5. Keefe says their power play has been good, but wants more.
"Obviously getting clean looks has been a challenge," Keefe said. "But at the same time, we've found a way to score pretty consistently. If you're getting one power-play goal a game, you'll take that."
