John Karalis of Red’s Army and the “Rainin’ Js” podcast joined Downtown on Tuesday to talk about the upcoming game against Memphis on Wednesday and what went wrong against the Cavs this past weekend. Karalis said that the Celtics learned that they shouldn’t be complaining to the refs as much, but were able to learn something from the loss. He spoke on the break for the Celtics and said that it was the perfect timing for the team to get on the same page at practice. Karalis also listed the reasons as to why the Celtics are serious contenders to land a big time free agent this off-season and next.
