Sweeney has his warts but to suggest he is in the bottom half of the league as a GM (so far) is a pretty dumb take IMO. W/L matters and the next 3 years (if me makes it thru them) will be extremely telling on where he and his staff sit as they no longer have the home town discounts of the guys who have left, and will need to retool on the fly and hopefully put the team in a position to make a run in the coming 3 years before the new core starts approaching the peak and back nine.
Undrafted college guys can only get you so far and as much as you can find a diamond where no-one was looking, probability and history suggests the guys are journeymen players in the NHL as complementary guys but not people you build your core with.
