Feel like Jagr is the same as Iginla. Adding more talent to a position already loaded.
Jagr's a winger. Hawks have plenty of Top 6 wingers. Center is what ya need. If this move comes with the caveat that Sharp move to 2C, Bolland moves down to the 3C, someone from the third goes back to the 4th, then I'm all for it. But Sharp at 2C has been a possible solution for nearly three seasons now and it still hasn't happened.
Sharp has supposedly been pretty strong in his wishes to play wing. I'm guessing we would have seen him at 2c over the last few years if that was even an option, so I would be surprised if it did happen at this point.
Jagr isn't the type of player the Blackhawks should be trading for, especially at that price. Jagr would probably help out on the PP though, an area of need but I don't know where he would fit in top 6 without Kane/Sharp moving to center. I much rather have Clowe (not going to happen with several contending teams hot after him) than Jagr if the Blackhawks are going to go for a winger, which I don't think is an area of need in any way. Especially when you consider that Shaw and Kruger both might be better suited as a winger.
2c in some form should be the area of focus. Bozak, Ott, Roy, Ribeiro, Stastny, Vermette, Gagner, Nielsen, and Jokinen are all "possible" 2c guys that could be moved depending on what their teams plan on doing. I'm not a fan of all of those guys I just listed, but those seem like the more obvious options out there for that position. Some guys are fringe guys, not very physical, would cost too much, etc but those are the options as I see them.
Something that I saw elsewhere that is important to note is that the Blackhawks are currently at 50 contracts after the Handzus trade. You cannot have more than 50 contracts for your organization. If the Blackhawks do make a deal from here on out, they won't be doing so with picks and picks alone. It would take a roster player or prospect so they can stay at or under the max contract amount.
