According to ESPN’s Chad Ford, ‘increasing belief’ around the league is that the Celtics will attempt to trade Rondo for multiple assets when he returns to health:
All three of the teams ahead of [the Celtics] have at least one young player they can conceivably build around. The Celtics? Rajon Rondo could be that building block. But he turns 28 in February, has posed chemistry issues in the past and there is an increasing belief among NBA circles that GM Danny Ainge will use him, once healthy, to get multiple assets back. So the chances that he’s the Celtics’ cornerstone moving forward look slim.
Ford tends to be a bit hit or miss with his reporting, so it needs to be taken with a grain of salt. Still – the fact Ford seemingly pulled that from ‘NBA circles’ is a little telling.
What exactly the Celtics are looking for in return is currently unknown though as noted, they have plenty of holes to fill.
If made available, just about every team in the league would put forth an offer for the former Kentucky Wildcat.
