NHL: 3 things to know for Wednesday night

Only three games are on tap in a typically light Wednesday night in the NHL, but two of them involve Canadian teams. Here's your cheat sheet for tonight, including notes on the Calgary Flames' baseball-like schedule and the ongoing defensive struggles of the banged-up Edmonton Oilers.

Bad Bruins

The only All-American game of the night is an Original Six matchup between the Bruins and Red Wings in Detroit at 8 p.m. ET. These teams played last Thursday and the Wings won 2-1 at home.

Boston has won its division in each of the last three 82-game seasons, but the Bruins are off to a slow start at 1-3-0 and are averaging exactly one goal per game. Last season's top scorer, David Krejci, returned on Monday, but he was held off the scoresheet as his team lost 2-1 on a buzzer-beater by Colorado's Danny Briere.

You guys wanna play baseball?

A night after beating Nashville in a shootout, Calgary plays game No. 4 of its six-game road trip at Chicago at 8 p.m. ET. The Flames (2-2-0) are in the midst of a baseball-like schedule to open the season, alternating extended road trips with home stands. After opening the season with one game at home, Calgary has the aforementioned six-game trip, then five at home, then five on the road, another five at home, then three on the road to close November.

The Blackhawks should be well rested. They've played only twice (both wins) and not since Saturday's 6-2 home win over Buffalo.

Oil spill

The late game has the Oilers in Arizona to face the Coyotes at 10:30 p.m. ET. Edmonton (0-2-1) is still struggling with the defensive issues that plagued it last season, when the Oilers gave up the most goals in the league and finished well out of the playoff race. It's more of the same so far this season, as Edmonton is one of only four winless teams (joining Carolina, Florida and Philly) and is again worst in the league in goals allowed per game at an even five per match.

Edmonton is coming off Tuesday's brutal outing in L.A., where forwards Jordan Eberle and Ryan Nugent-Hopkins sat out with injuries (coach Dallas Eakins called them "day-to-day") and the Oilers were routed 6-1 by the Stanley Cup champs. Making matters worse, goalie Viktor Fasth left in the first period with a groin injury.

The guess here is that Ben Scrivens, who allowed three goals on 15 shots, will get the start tonight.
