The report said MKG is not available, so I think we should temper expectations.
I like Bass for Biyombo. Charlotte would need to pay another team cash to take on a minimum salary player, or we'd have to waive someone to take on an extra player since the numbers don't match up perfectly, but I think that's more the speed of what the Hornets are willing to do.
Biyombo also fits into the Joel Anthony trade exception, meaning we could get a new exception for the complete value of Bass' contract, so $7 million, which could prove useful down the line. Some sort of second-round pick would be nice, but added luxury tax flexibility and a large exception allows you to pick up those goodies down the line. A 4-month audition for Biyombo before he becomes a restricted free agent would be worth it.
