PRO: Offense
Basically, if the Cavs trade for Kevin Love, they would have to part ways with Andrew Wiggins. Wiggins has the potential to become one of the better two-way players in the league after a couple of years. He has great athleticism, has improved his shot tremendously this offseason and is a great player on the defensive end. However, Kevin Love would bring instant offense to the team. Adding Kevin Love would make them even more of an offensive threat immediately and would give them a better chance at winning that championship.
In Miami, LeBron improve his pick and roll game tremendously. Love would make the perfect partner in crime to make those pick and roll plays more effective. Either LeBron will go through with it and get to the basket or he will get double-teamed leaving Kevin Love wide open for a three-pointer.
There is no doubt that a starting team including Kyrie Irving, LeBron James and Kevin Love would be dominant. The Eastern Conference is a weak conference compared to the Western Conference. Having that much of a dominant offense in the East would make it quite easy for the Cavs. It would probably be easier for them to make it to the NBA Finals than it was for Miami the four years LeBron was there.
