Fluto on Toucher and Hardy was very supportive of Sweeney and lauded his work with UFA's this past summer stating that this team wouldn't have had near the success they have without Heinen, JVR, Geekie, Shattenkirk, Boquist, etc and that he deserves the benefit of the doubt on Peeke. Went on to say many players have come to Boston and have found their identities under the tutelage of the staff.
He included Linus Ullmark in this discussion, citing his decision to stay in Boston was clearly based on the fact that he loves being a Bruin, but also...Boston is where he developed into an elite goaltender.
So, while I agree that Sweeney has made a few head-scratching moves over the years, he has a remarkable history of finding talent in less obvious places. Sweeney was flamed when he took Mason Lohrei in the 2nd round ahead of a long list of "notable" prospects. Look at him now.
If you remove the 2015 draft (where he deferred to the existing scout team), his draft history is better than he gets credit for. His trade history is fine too. And recently, his UFA signings have been solid.
I think the negative response to the trade for Peeke is appropriate given the price paid and the fact Peeke has regressed badly in CBJ, but I think Sweeney works in mysterious ways and there is a chance Peeke develops into the player (or something close to the player that earned him a call in the 2nd round in 2016.
