Considering what little they had to work with, the Mavs offseason is off to a bang-up start. They turned a draft pick into three players; dumped Davis Bertans contract; signed one of the best shooters in league history on the cheap; and retained Kyrie Irving s services at a discount. Heck, Nico Harrison did such a good job on the last item, Kyrie might not even have time to get antsy before the deal is up.
