The Boston Celtics didn't sign a star this summer, but they did add two veteran forwards who really know how to play the game, and will perfectly compliment Brad Stevens' system.
For that, NBA GMs showed Boston some love in their annual survey. Both Lee and Johnson received 6.9 percent of the vote for the question: "What was the most underrated player acquisition?" Lee and Johnson will almost definitely improve Boston's offense, and Johnson should impact the other end of the floor.
These two are a significant reason why most people are starting to think the Celtics will sneak up on some people this year. Just how far do you think they can go?
