Ainge was reportedly interested in Paul Millsap, so if the Celtics could have worked out a sign-and-trade for Millsap (presumably meaning that Kelly Olynyk would have ended up in Utah), gotten a veteran like Beno Udrih to hold down the starting PG job until Rondo returned, and picked up a veteran center for the minimum to eat up center minutes and help preserve KG, would the Celtics be playoff contenders?
A starting lineup of Garnett, Millsap, Pierce, Bradley, Rondo and a bench of Sullinger, Green, Udrih, Bass, that veteran center, and maybe Lee and Crawford are still around
