If the trade was exactly as shown and we gave the MLE to Hood (so minus ET and Hark, plus Wiggins and Hood):
Hard cap: Approx $138,000,000 (estimated until new league year exact numbers are set)
Pre-signing Hood: $123,611,711
After signing Hood: $132,857,711
So we'd have roughly $5,142,289 to play with but couldn't go over that amount for any reason. We'd only have 10 players on our roster so we'd have to sign at least 4 or more likely 5 with Nurk being injured.
Minimum Salary for undrafted rookies: $897,158
Let's say we signed 3 of those guys at that price. That leaves us $2,450,815 to sign either Aminu or Layman (could only sign one) or to sign one other minimum contract guy who has 9 or less years of service.
Conclusion: Adding Wiggins via trade and Hood for the full-MLE pretty much screws us this season unless another trade is made too, say dumping Leonard's contract or something like that.
