LeBron James had monstrous numbers in the 2015 NBA Finals averaging over 35 PPG and over 13 RPG. But he concluded with, "we ran out of talent." And to his credit, that's true. Kevin Love missed most of the playoffs and Kyrie Irving the final five games of the Finals.

We thought a healthy Cavaliers team would be better suited to challenge the Warriors. But that's clearly not been the case. Cleveland has updated their surrounding pieces, adding Channing Frye and Richard Jefferson. And this time, Love and Irving are playing.

But it's not making a difference.

LeBron seems to be doing it all again, and his teammates aren't holding up their end of the bargain, regardless of the "numbers" in the box score. So what was different with the Miami Heat when Dwyane Wade and Chris Bosh were on his side? I've got three things that I think the Heatles offered that this new Big 3 do not.

1. Defense

There's a big reason why the Warriors are very content continually involving Kevin Love in their pick-and-roll scheme: it's because he can't play defense. And Kyrie Irving, although he gets his hands on the ball often, isn't a one-on-one defender that you trust.

Dwyane Wade has been on the NBA All-Defensive 2nd team three times in his NBA career. He has a reputation for being able to defend and wanting to do it. Wade was never a liability on defense...except for when he wouldn't run back (we've all seen that before). And Chris Bosh, who admitted he wasn't a good defender, became a good defender. He used his length to change the game for the Heat and continually took on stronger players in the post.

Love and Irving are often the weakest defensive players on the their team when on the court. Teams go away from LeBron, Shumpert, and Tristan Thompson. But they attack Love and don't have a problem going iso on Irving. It makes a difference, and I think LeBron can recognize when the effort isn't there. Sometimes it's so clear to see the frustration on James' face when Love misses a rotation or doesn't do the right thing. Defense matters and it's something Wade and Bosh knew how to do.

2. Off the ball activity

The biggest impact that Love and Irving have on the game is when the ball is in their hands. I'll give Love some credit...he can be a tremendous rebounder, one far better than Chris Bosh. And Irving has a one-on-one game that is very good and bails them out often.

But when they don't have the ball, they are idle, out of place, and hesitant. Wade and Bosh had to learn this, but it only took one season. When Christmas Day 2011 rolled around, they had it figured out. Chris Bosh learned how to perfectly space the floor for his teammates. Dwyane Wade learned to perfectly cut at the right time for LeBron to open up the game. They both knew how to make an extra effort to make themselves noticed even without the ball.

LeBron doesn't have that commitment and luxury from Love and Irving. He is the one who has to do those things off the ball. He has to do it with the ball, off the ball, on defense, leading in the huddles, etc. He does it all, and it's a heavy weight.

3. Experience & Brotherhood

When Wade, Bosh, LeBron and the rest of the Heat organization played at Quicken Loans Arena in November of 2010 it solidified a bond in them that created an US vs the THEM mentality. They became brothers when they went into the most hostile environment we have seen in the NBA since the brawl at the Palace of Auburn Hills in 2004. It changed them.

They became united and cared for each other off the court even more than before. And that love and relationship carried onto the court in chemistry. They had an understanding, a respect.

Remember, as you know, Wade was already a Finals MVP before LeBron landed in Miami. Both players had playoff experience to offer. You know who doesn't? Love and Irving neither had played a playoff game before LeBron came. He has had to teach along the way -- TEACH his co-leaders of the team about the playoffs. The experience, the brotherhood, the respect...it's a whole different relationship in Cleveland than it was in Miami.

And that makes a difference.

LeBron is missing integral parts of leadership in Cleveland right now that he never had to question in Miami.

Can he overcome it?
