If he works hard he could be what Lu is. They kinda have the same skill set. Barnes doesn't have as much bball iq or defensive prowess. Barnes is a ill more athletic and has a better mid range and long range shot at the same stage but right today deng is a better shooter from both ranges.

I could see him working well with Kyrie if Byron coach 'em up and with both Kyrie and Tristan there they won't have to depend on Barnes to score. But lamb (the uconn one) is prolly a better fit for their future.
