Decisions, decisions. The Celtics don’t have many free agents, but with the rest of the league passing them by, they have to take a serious look at each player on the roster and decide which direction they’d like to go. Core players Kevin Garnett, Paul Pierce, and Rajon Rondo brought Boston a championship, but they could also be valuable pieces on other teams. Jeff Green has emerged as a big-time player, but can they build the team around him? Was Avery Bradley’s season a hiccup or a sign of reduced expectations? The decisions the Celtics make this offseason could have ripple effects for years. In the slides ahead, we examine each of them and ask for your input on transitioning the Celtics toward the future.
