I think the Sprong move comes in just under the Ziggy and Mantha/Jake debacles. He had two things going against him (here) though. He was fast and wasn't afraid to score.
Well Sprong...they were (at least Lavi was) unhappy with him for some reason, but I think also he was about to be a FA, so they moved him to get at least something cause no way could they afford him in FA the next year.
Mantha/Jake...well I'm not sure it was a debacle...well more like I guess a debacle for both teams. That trade didn't help anyone except to get Mantha a contract he didn't live up to. I actually liked the trade at the time. (other than I think we spend some other assets too)
I hated seeing them let Ziggy walk, but same deal...they were not going to be able to afford him due to the cap trouble. I thought he was a perfect and rare (these days) defensemen we really needed. So dumb to let him go.
I think his loss hurt less than it should have only because TVR and Jensen played....prolly better or above their normal/previous level for the next few seasons.
Geez who the F created the Caps schedule this year. This is dumb. 3 games in four days with a back to back then 2 days off, then 1 game, then 3 days off, then 1 game, 1 day off, 1 game, 2 days off, then 3 games in 4 nights with another back to back
