I've always felt when they've used the term "aggressive" it was linked to things like them trading for Fox, moving up for K Miller, trading McD/JT Miller with a year left on their deals instead of waiting until they were pending UFA/RFA.
Similarly when I hear them use the word "accelerate" pertaining to the rebuild, I think of trading for already drafted prospects. For every one of those who works out it accelerates the rebuild.
"Patience" I tend to take it at face value, I think they are talking about letting the process play out. Seeing what all these prospects do as they develop.
No "shortcuts", similarly I think they are talking about not trying to hurry the process along. Avoid just making the playoffs be the priority, more build a roster that can make the playoffs and if so, has a decent chance at advancing it them.
That said, I really hope they figure out the AHL as that would certainly fit in with the patience and development parts. Not so much wins and loses, more making sure that is a optional and fruitful step along the way to the NHL since some of the prospects are likely going to need it.
