I think this is going to be LeBron's biggest challenge by far during his NBA Finals run to keep the streak going this year. He essentially has a brand new team now and just two months to get everyone integrated into what he wants to do before the NBA Playoffs begin. That combined with the Boston Celtics being one of the bigger Eastern Conference roadblocks he's faced in the long while; he will certainly have his work cut out for him. I think the Celtics' pickup of Greg Monroe as well has been fairly under the radar, but potentially impactful as well. The rest of this NBA season with the Eastern Conference will certainly be very compelling and then the drama will shift to whether LeBron decides to return to the Cavs for next season. The NBA is never boring!
