I mean you hit on the areas Glendening is superior to Andersson, but neglected the other side. Andersson has more offensive ability (not saying much compared to Glendening), is better at faceoffs and penalty killing, while being very comparable defensively to Glendening. So far, Andersson's best showing of hockey (playoffs 2013) is more impressive than anything Glendening has displayed. Again, I don't really care if either is on the team, but I think Glendening is severely overhyped because of the agitating angle.
I guess we will just agree to disagree on Jurco. I don't really care about losing players for nothing if they are expendable for starters. If Callahan is worthy of a roster spot, that's what the pre-season is for him to go out and earn it. The Red Wings can't afford a ten game tryout for the regular season since they are more than likely going to be fighting for their playoff lives again.
IMO that's not what you want from a 4th line C or any 4th line player. You are on the 4th line to shutdown defensively and fight, check, and agitate. Everything the top lines don't do. Andersson has a good defensive mindset and can win FO's but Glendening is a gym freak, mouth running, maltby type. I'd take his 7 pts over Andersson's 17 pts on the 4th line everyday of the week. Plus Glendening is tremendously faster than Andersson. Speed has been the name of the game for years now.
The point I'm advocating is keeping our top guy (Jurco) while also giving our unproven guys a chance. I think that's incredibly fair. Everyone stays with the team as long as they perform. Jurco was good, but was by no means the difference maker. You act like if he doesn't play the wings are going to lose those first ten games. He was secondary support at best. That, of all things, can be gambled with for the betterment of the team as a whole...
