More NHL offseason: Rumors | Top 50 Free Agents | Buyout Tracker | Trade Tracker

According to a report from the Boston Herald, the Bruins may have decided to trade Tyler Seguin, at least in part, because of his off-ice partying.

From the Herald's Stephen Harris:

This trade might not be popular among all Bruins fans, who envisioned Seguin as a future superstar. But he might go down as a player who squandered his great gifts. Multiple sources said the 21-year-old Seguin crossed the line this season with reckless partying.

It apparently got so bad that during the playoffs, the Bruins ordered Seguin to live in a hotel, where a guard was hired to make sure he stayed in his room. But Chiarelli repeatedly defended Seguin, calling him “a good kid and a terrific player” and “a tremendous package of speed and skill.”

That all seems a bit extreme.

Less than a week before the trade, GM Pete Chiarelli spoke on the record that Seguin needed to become more of a professional, but insisted on Thursday he was only referring to his pre-game preperation and not his lifestyle off of the ice.

The Philadelphia Flyers and Chicago Blackhawks faced similar situations in recent years with young players acting like, well, young hockey players, and ended up following very different paths. The Flyers broke up their core of Mike Richards and Jeff Carter and watched them reunite in Los Angeles to win a Stanley Cup.

The Blackhawks were a little more patient with a player like Patrick Kane and were rewarded with their second Stanley Cup in four seasons and a Conn Smythe performance from Kane this postseason.

We'll see how it works out for the Bruins and Stars.

Dallas acquired Seguin and Rich Peverley on Thursday for Loui Eriksson and prospects.

Update: In an interview with the Toronto Star, Seguin's mother insisted that the Herald's report was not true and that the entire Bruins team stayed in a hotel during the Stanley Cup Final.

That’s not true,” Jackie said, adding that she and her husband, Paul, spent much time with their son in Boston during the Stanley Cup final.

“I know that for a fact,” she added, her voice rising. “The whole team lived in the hotel. That’s crap. Oh, my God. That’s stupid stuff. That’s very unfair to say that. He’s a professional. That makes me very angry.”

She went on to say that Boston is now going out of its way to justify the trade so that there isn't a backlash against Bruins general manager Peter Chiarelli.
