Speed and quickness is the highest priority, this team is small and average skaters which is a bad combination.
Not so much straight line speed but the ability to juke people and enter the O-zone, Ghost had that as a rookie but lost it, no one else really can "shake and bake." Don't need 12 of these forwards, but 2 or 3 (Frost? Farabee?)
One or two snipers, guys who can beat goaltenders inside 20 feet with a quick wrist shot - Flyers set up scoring chances but can't close the deal, too many muckers and passers.
Better balance, need a veteran top 4 RHD to stabilize the defense, too many inexperienced LHDs on this team, Gudas is solid but not a top pair guy.
Patience, a lot of top talent is on its way, no need to rush them, the object isn't to field the youngest team, or squeeze into the playoffs, but build a SC contender that can do it for a decade (see the Caps) and thus increase the odds of the Hockey Gods smiling up on them. Same with guys like TK, Patrick and Sanheim, lower expectations and accept it may take a couple years for them to peak.
And of course, Hart has to learn to walk on water.
