"It's a good test, but makes it a super long day getting prepped for the main game," he said. "I've been here since Feb. 8, and we've had some cold stretches and some long nights. Fortunately for us, the last couple of days have been a little better and have just given the crew more of a break; instead of working the 15-hour shifts, they are just working the 10-hour shifts.
"So they almost feel refreshed and it's a good chance to give them time here to take a breath and focus on the next few days."
The only real concern prior to the alumni game will be the sunshine.
"The sun really affects our logos, so if the sun breaks out we'll cover up our logos for as long as we can and then hand-scrape them, add a little water, if that's what it is, and then the alumni game is good to go," Craig said.
TCF Bank Stadium is home to the University of Minnesota football team and, for the past two years, the NFL's Minnesota Vikings. Its capacity for football is just shy of 51,000, according to the school.
Craig also provided an update on the Stadium Series game between the Colorado Avalanche and Detroit Red Wings at Coors Field in Denver on Feb. 27. Craig's son Mike, who serves as NHL senior manager of facilities operations, is responsible for the ice at that location.
"Mike and his crew are doing a good job over there," Craig said. "They basically are using the formula that we used to set up in California when the Los Angeles Kings and Anaheim Ducks played (at Dodger Stadium on Jan. 25, 2014). At eight o'clock in the morning they put the tarps on and you can't take them off until 3:30 p.m. That's when you work until 4 or 5 in the morning and then put the tarps back on.
"It's a very condensed setup, and as long as we're prepared for it, everything moves along well."
