They're the big anomaly though in that they basically did rebuild from Day 1. They leveraged cap space and threats of taking players (or not) into Smith/Marchessault, 1st and a 3rd for taking Thorburn, 2nd + Gusev from Tampa, 1st and 2nd from NYI, Theodore from ANA, Tuch + 3rd from Minnesota, 1st and 2nd from CBJ, and 2nd from PIT.
So starting at Day 1 as a franchise, they had a lottery pick in their first draft, all of their own picks plus they got like 8 more 1st and 2nd round picks, a Norris caliber D-prospect (Theodore), and an A/B prospect in Tuch. All of that plus whatever they were actually able to take off of other teams (that they got insanely lucky with everyone hitting - Smith, March, Karlsson, Miller, MAF).
Any team undergoing a rebuild could only dream to be able to acquire the prospect and pick haul that Vegas did simply by existing and having the expansion draft rules catered to them (relative to what SJ endured). They made some really bad trades and it didn't even phase them because they had so much currency (which is the whole goal of a rebuild - accumulate currency in young players, picks, prospects).
