Personally, I see the lack of movement at the deadline as likely one of two things.
A) Ownership handcuffed Blake at the deadline due to a lack of faith in his 'plan'
- He claimed he's built this team specifically to beat Edmonton, PLD was a HUGE swing (and so far a huge miss), and there's a number of other mistakes on Blake's record that should give an ownership group pause
B) Blake truly believed this team was good enough to contend at the deadline
- Which is so insane it should lead to his firing if that's the case
Basically, it was either Blake's fault for not improving this team at the deadline or it was due to ownership running out of confidence in Blake's ability to make moves that benefit the team/organization. Either way, it very much hints at Blake being on the way out (short of a miracle run by the Kings).
You can't make a trade like the PLD trade and then sit on your hands at the trade deadline and lose in the first round (for the 3rd year in a row to the SAME team) and keep your job. So as others have pointed out, the silver lining is either we win in the playoffs or we at the very least see a new GM take over (ideally more front office changes than that).
