Its worth floating I guess. The problem as i see it here- is that the assets you are trying to move are at an all time low. Its smart asset management if you can make it work- but if I were the other owner- this would have very little appeal. Heres why:
Kapanen- Just got traded to the maple leafs. He went from possibly auditioning on Crosby's wing- to an absolute trainwreck that is most likely in the 4-6 year range away from resembling anything halfway consistent. This would be bad for any established player but imho is far worse for a prospect- because there is never an absolute guarantee with them anyways (outside of the very top picks). Im unfortunately a KK owner and this was brutal news as an owner. I felt like I had a medium risk/sky high reward chip days ago and now I have just another medium risk/medium reward piece that ultimately is not very interesting.
Trouba- As a jets fan- I love this guy. Last season really started to put the fear in me as a fantasy owner though. Im legitimately worried about his offensive upside now. So much so that I dropped him from my keeper team- something I said Id never do (I had an excrutiating decision earlier in the season and actually dropped Rielly to keep Troub). They seem to be grooming him as a defensive specialist- and it was never so evident as the distribution of pp time and key offfensive minutes afetr the Myers trade- Tyler got the lions share by a healthy margin. Yes thres still hope- but again his percieved value is just very low right now.
Im not huge on the COL guys (Barrie really does not shoot enough for my liking)- but both of them had above average seasons on a team that didnt fare very well.
So yea- float away- I think if it happens you win in the short term (and the way things look today- most likely the long term aas well)- Im just saying why id be skepical. Its not an insulting offer though- its worth putting out there. Good luck!
