There can be little debate over the fact that the Tomas Kaberle acquisition has not provided the kind of oomph the Bruins expected it to do.

The power play was not cured of all its ills after the slick defenseman was obtained from the Toronto Maple Leafs on Feb.?18. And in the last two games of the Philadelphia series, Kaberle saw his ice time dwindle to under 14 minutes each game.

But with the Bruins starting their Eastern Conference finals against the Tampa Bay Lightning tomorrow night at the Garden, there is still time for Kaberle to provide that little something extra from the back end for which the B's have been yearning. Each game now carries such magnitude that whatever he can do from here on out has the potential to erase any shortcomings that have been evident in his game thus far.

After all, there weren't a lot of people lauding the Chris Kelly pickup after he notched just 2-3-5 totals in 24 games in the regular season, but it's amazing what a couple of clutch playoff goals can do for a player's perception.

And while it's a stretch to suggest Kaberle was an impact player in the Philadelphia series, he did start playing better, as coach Claude Julien pointed out earlier this week. Though Kaberle saw less ice time against the Flyers, he was a plus-4 with an assist in the series sweep. The B's also scored a couple of power-play goals late in the series, first a confidence-building 5-on-3 goal to break a 0-for-30 skid, and then a big 5-on-4 goal in the first period of the clinching Game 4.
