It could still be dangerous, if they move Iggy to SG and have Barnes start at the 3. JJ and Kevin could then help solidify their bench.
When I first heard about it I initially thought it was a downgrade, but if Iggy is moved to the SG position it could create some problems. Barnes can defend the bigger player and Iggy can shut down the more dangerous guard. You can then hide Curry on the weakest option defensively. Love is a rich man's Lee in my opinion with a decent 3 pt. game.
