It's funny how the Flyers clearly won both the Richards and Carter trades (Columbus got seriously traderaped by LA though), yet they are way worse off now than before the trades. Part of that is using the saved cap space on Bryzgalov, but the main reason is the cluster**** that Holmgren has assembled on D.
Pronger, Timonen, Carle, and Coburn was probably the best top-4 in the league. But Holmgren decided to replace puck-movers such as Pronger and Carle with stiffs like Grossman and Schenn (and later tried to rectify it with signing the corpse of Mark Streit and trade for one of the leagues worst and most overrated defencemen in MacDonald). The Flyers have an amazing forward corps that is being held hostage by a defence that can't skate or move the puck if their lives depended on it.
Timonen is still amazing and can go toe-to-toe with the best, and dominate the easier matchups. Coburn doesn't do much in soft minutes, but he performs above expectations in the tougher minutes. Streit is slightly below average in most situations, and downright terrible if he gets caught against elite players. Schenn is actually a poor-man's Coburn and isn't entirely horrible against tough comp, but does nothing with soft matchups. MacDonald is overall terrible unless he gets to play against goons and/or AHL'ers where he does very well. Grossman has been too injured the past three seasons to make a statement about his play, but his numbers are overall dreadful.
If Timonen retires this offeseason and doesn't replace him with legit #1 (which he still very much is), the Flyers will be in the hunt for McDavid.
