Seeking to make roster upgrades this summer after losing to the Cleveland Cavaliers in the Eastern Conference Finals, the Boston Celtics will reportedly make Blake Griffin and Gordon Hayward their primary free-agent targets.

On Wednesday, The Vertical's Adrian Wojnarowski explained on his podcast what he thinks the Celtics will do in free agency this offseason, via Ryan Snellings of FanSided.

"Boston is really the danger for Blake Griffin," he said. "I think Boston's two primary free-agent targets, right now, are Gordon Hayward and Blake Griffin. Now, they're not going to get both of them, but they're both players that would potentially have interest there. I think Boston looks at in different ways with their future."

Both Griffin and Hayward have opt-out clauses in their current contracts that could make them free agents in July.

The Celtics have been linked to Hayward for some time due in part to his college days at Butler, where he played for Boston head coach Brad Stevens.

Fans in Boston even cheered Hayward prior to a January home game against the Utah Jazz. The Jazz will still be able to offer Hayward more money than anyone else, though the team missed out on being able to extend a super-max deal when he wasn't named to the All-NBA team.

Broderick Turner of the Los Angeles Times reported April 30 that the Los Angeles Clippers and Griffin hope to work out a max contract that could pay him up to $175 million over five years.

Griffin has been hobbled by injuries, appearing in just 96 games over the past two seasons, but he is a dominant force on the court when healthy. The 28-year-old averaged 21.6 points and 8.1 rebounds per game last season.
