Capela will certainly be better in the next 5 years, but we should only really care about comparisons for the next 2-3 years. I would trade Capela for someone who will be better than him for the next 2 years. Still, I don't think Love makes a greater impact on the court than Capela starting right now.
They are completely different kind of players. Capela is primarily a defensive presence; Love is a shooter.
