The biggest roster surprise of the day comes from CSN Chicago's Tracey Myers...

As the Chicago Blackhawks closed in on their final preseason game, they added a very familiar face to the training-camp roster.

The Blackhawks added Daniel Carcillo to their roster on Friday, a surprise move within a week of the team starting the regular season.

(that and the Hawks' status as over the cap's upper limit, needing to clear a Capgeek-estimated $2.216 million from their books by Tuesday at 5 PM)

Carcillo spent two seasons with the Blackhawks, although he didn't have great health during his time here. He suffered a season-ending knee injury in January of 2012 on a hit that also got him suspended seven games. He had another knee injury in the Blackhawks' 2013 season opener against the Los Angeles Kings. That led to Brandon Saad joining Jonathan Toews and Marian Hossa on the top line, a combination that proved tremendous in the lockout-shortened regular season.

And as I've seen the "Dry Scrape" in action on a repeated basis at the Red Wings' prospect tournament, I feel I'm qualified to weigh in on this story from Yahoo Sports' Neate Sager:

Say this for the Ontario Hockey League, it was quick to react to a new rule that was obviously going to slow down games.

To mirror the NHL, over the summer the major junior leagues adopted the big league's new rule of giving the entire ice surface a dry scrape before the start of the 4-on-4 overtime, rather just freshening up the middle of the rink once a shootout was required. Out in the Western Hockey League, it was quickly discovered that the change entailed significant delays in arenas that only use one Zamboni. Since the OHL does not play overtime in preseason (games that are tied after 60 minutes proceed directly to a shootout), there was probably a slower realization of how the switch would inconvenience fans. Suffice to say, all it's taken is one 11-minute-long de facto intermission between the third period and overtime of a London Knights-Owen Sound Attack game on Sept. 26 to realize it was time to go back to the old rule.

The OHL’s experiment of scraping the entire ice surface at the end of regulation time, however, is over. That’s due in large part to the Knights-Attack game, when it took more than 10 minutes to resurface the ice with just one Zamboni.

“You’re just sitting there doing nothing, waiting for the Zamboni to finish,” [Knights goalie Michael] Giugovaz said. “It was really weird.”

There are four cities in the league — Owen Sound, Sudbury, Belleville and Peterborough — that operate only one ice-resurfacing vehicle.

“In order to be consistent around the league, we’ll revert back to the old way (a couple of Zamboni passes down the middle of the ice before the shootout),” OHL vice-president Ted Baker said. “It was evident it was too much of a delay for the fans and the players.” (London Free Press)

Now the dry scrape with one Zamboni isn't pretty--it certainly lets some air out of the pre-overtime balloon--but between the dry scrape and the "long change," the vast majority of games at the Wings' prospect tournament were solved in some really exciting overtimes...

And the players and coaches were blunt about the situation. They didn't mind it at all and liked the OT changes, but what they really wanted to do was to be able to go back to the locker room for the 5-10 minutes (usually six with two Zambonis), get some fluids in, take off their jerseys to cool down for a minute and maybe go over game strategy instead of sitting on the bench and waiting.

TSN's Darren Dreger mentioned that the NHL's still struggling with ways to tell fans and players that the dry scrape is taking place during last night's Insider Trading video, suggesting that the league may implement a 5-minute "countdown clock" to let everyone know when to be ready.

Having seen players skate on relatively fresh ice and have to make long changes as opposed to muddling through slushy guck en route to a shootout, I think the idea is fantastic, and it works, but it has to be tweaked to get the coaches and players to buy in.
