2008-09: Connelly made his pro debut with AHL Rockford after signing an entry-level contract with Chicago in March 2009 following his junior season at Colorado College. In nine games with the IceHogs he had a -2 plus/minus while scoring 1 goal with 2 assists. He skated in 3 of 4 playoff games for Rockford and was -2 with 2 PMs. He skated in all 38 games for Colorado College before joining Rockford. Connelly led all defensemen with 24 assists and was -1 with 3 goals and 46 PMs as the Tigers finished third in the WCHA during the season but did not receive an NCAA bid after being swept in a two-game WCHA first round series.
2009-10: In his first full pro season out of Colorado College, Brian Connelly's play has been one of the key's to Rockford's season. The offensive defenseman is not only a good puck-mover but he is a good skater and can lead the rush.
2010-11: Connelly again paced Rockford's blue line with 11 goals and 52 points in 80 games. His point total was second best overall on the team as Connelly played on the top pairing and top power play unit throughout the season.
He has played a role on the power play where he has more freedom to pinch or get his hard shot on net to create chances. Though not exactly intimidating defensively at 5'10 167 lbs, he uses his speed and awareness well in his own zone.
Connelly will be a top offensive option for Rockford's blue line in the 2011-12 season. He will be looking for an opportunity at the NHL level after two productive AHL seasons, but has yet to get a look with the Blackhawks.
