My point is this. To get the best value for Irving Cleveland need to deal Love as well.
Assuming this is happening and Lebron is leaving you do 1 or 2 consectiutive trades involving a total of 3 or 4 teams. You trade love for a PG, a wing and a pick/picks while you trade Irving for a Big, a wing and a pick/picks
In this sitiation you Swap 2 stars + roster chaff for 4 players (2 of which have unproven/lesser star potential) you get younger/better wing depth and potentially 2 or more future firsts.
Cleveland has everything they need to be contenders (Lebron + 5 solid prime age starters) plus a few picks in case they need to rebuild.
Thats the type of deal/deals Cleveland need to make. Then just cruise through the East and hope GSW SAS HOU and OKC beat the crap out of each other enough that you can beat GSW.
