By Tim Healey/DFP StaffThe Youngstown Phantoms added Boston University forward Brendan Collier to their roster last week, a move akin to the one the Indiana Ice made when they added Sam Kurker earlier this month.In both cases, the mere addition of the player to the USHL roster does not mean they will leave the Terriers. Similar moves are often made out of speculation — sometimes informed speculation — of a given player’s happiness with their college team.Collier, a Charlestown native, has registered one point (an assist Dec. 7) in 11 games during his first semester in the scarlet and white. The longest stretch of games in which he sat was three when he didn’t play the second half of November against North Dakota twice and Cornell.Kurker and Collier are still listed on the BU’s official roster.
