Anyone who thinks the Cavs should not trade Wiggins for Love is either out of their mind, or they don't really know how good Kevin Love is. He averaged 26 and 12.5 last year. That's more points than James Harden and more rebounds than Dwight Howard. He is arguably a top 5 player in the league. After Lebron and Durant, he's in the conversation. The only arguments I hear about him not being a top 5 player are that he's a poor defender and that his teams don't win.
The Wolves are my #2 team, and I watched 60+ of their games last year. Love is not a bad defender, he's just not a rim protector. He plays solid positional defense. The fact that his team has never made the playoffs is more to do with bad roster construction, mostly bad coaching, and poor management. In addition, playing in one of the toughest and deepest conferences in NBA history doesn't help. They would have been between the 3-5 seed in the East.
Even if Wiggins ends up being as good as Love (which I doubt), his prime won't overlap very will with LeBron's. Kevin Love is currently 25 years old. He's just starting his prime years. He's also a perfect complement to a guy like Lebron. He's a unique player that will both space the floor and bang in the middle for rebounds. They will immediately become the favorites in the East with a punchers chance to beat whatever team comes out of the West.
There is virtually no argument here, which is why Cleveland came off their position so quickly and are now offering Wiggins + more for Love.
