Why do you pay Weber 25% of his contract for one year of play and then deal him?? The return would have to be astronomical.
What is likely going to happen is Poile and Homgren will work out a trade this week for Weber. This offer sheet was probably done to force the trade. The return for Poile will likely be pretty good. It will be better than 4 1st round picks. He can negotiate with Holmgren all week.
If you're Poile, you have to look long and hard at 4 1st round picks as compensation (as is speculated by TSN). Not sure what Phily have on their current roster/system that would be better than that unless you're getting Giroux and B. Schenn - those would be the ONLY guys I would want from PHI.
