Pat Cannone and Connor Knapp helped Miami to a 2-0 start

The first weekend of the regular season featured plenty of surprises and upsets. Of the 20 teams listed in the preseason USCHO/CBS College Sports rankings, 13 of them were in meaningful action over the weekend - and just two of those squads (No. 4 Miami and No. 6 North Dakota) would escape without tasting defeat. The teams in the lower portion of the rankings, in particular, struggled - as the bottom seven teams (ranked Nos. 14-20) combined for a 3-10-0 record, including 2-7-0 against unranked opponents.

Miami - which was the top-ranked team in the preseason USA Today/USA Hockey poll after barely falling short in last year's NCAA championship game - had one of the most-impressive weekends of any team, as the RedHawks earned a home sweep of 15th-ranked St. Cloud State. Junior All-America forward Carter Camper scored the game-winner in overtime in a 3-2 victory on Friday. The following night, it was sophomore Connor Knapp earning a shutout while junior forward Andy Miele had the primary assist on both of Miami's goals - scored 20 seconds apart early in the third in the 2-0 game.

The other marquee series of the weekend pitted No. 1 Denver against 14th-ranked Vermont, a Frozen Four participant last season. The offenses were in high gear, and the weekend ended in a split. UVM appeared to be on its way to spoiling the first game of DU's 60th anniversary season, holding a 4-2 lead after two periods on Friday. But the Pioneers got a quick power play goal and then saw sophomore forward Joe Colborne net two more - one on the power play and then the even-strength game-winner with just over two minutes remaining in regulation - to give DU a 5-4 triumph. Vermont would not make the same mistake on Saturday, as senior forward Brayden Irwin scored twice in leading the Catamounts to a 6-4 win.

No. 6 North Dakota dominated Merrimack en route to a home sweep (5-2 and 3-2). The Fighting Sioux outshot the Warriors by a 75-35 margin, and freshman Mike Cichy had an outstanding first collegiate weekend with a goal, two assists and a +4 rating. Both games drew more than 11,000 fans.

The CCHA saw two of its teams ranked among the top five suffer opening-night defeats before rebounding for decisive wins - while two other squads claimed tournament titles. On Friday, Alabama-Huntsville tied the game in the third period and sophomore forward Cody Campbell scored on a wraparound with just five seconds remaining in regulation to give the Chargers a 3-2 upset win at No. 5 Notre Dame. The Fighting Irish outshot UAH 51-14 the next night in a 3-1 win.

Sophomore goaltender Scott Greenham registered the first-ever shutout for Alaska in 45 all-time meetings with No. 3 Michigan on Friday in a 2-0 decision. The Nanooks then claimed the Kendall Hockey Classic title with a 5-1 win over Mercyhurst. Greenham - who stopped 43 of 44 shots and also had an assist - was tabbed the tournament MVP. Michigan posted a 6-1 win over Alaska Anchorage the next night.

Nebraska-Omaha claimed the title in its Icebreaker tournament. The Mavericks scored three third-period goals to beat Army 6-4 on opening night and then upset No. 11 UMass Lowell 4-3 in the championship game.

Quinnipiac finished off a road sweep of No. 17 Ohio State with a 3-1 victory on Friday despite getting outshot 25-6 in the opening period. Bemidji State also swept a ranked team, with 3-1 and 7-3 victories against 19th-ranked Air Force in the battle of the Serratore brothers.

Other noteworthy results included Rensselaer knocking off No. 16 New Hampshire 3-1, Northern Michigan topping 18th-ranked Minnesota Duluth by the same score and No. 20 Northeastern splitting (2-4 and 4-3) a series at Colorado College.
