Two of the top five players in league, plus another arguable superstar joined forces last season with mixed results.
The Heat struggled at times last season and ultimately lost in the NBA Finals to the Dallas Mavericks, but the problems the Heat encountered were not due to the "Big Three."
Yes, LeBron vanished during the fourth quarter of several games, and Bosh struggled offensively at times, but those three are still far better than any other three players any other team could put on the court.
The teams who were able to find the most success against the Heat were teams with a top-tier point guard and/or post players.
The point guards the Heat put on the court were simply not able to stay in front of players such as Derrick Rose and Rajon Rondo.
Not only could they not stay in front of them, but they struggled to defend the paint once they beat their man off the dribble.
Yes, they did beat both of those teams 4-1, but struggled against them during the regular season.
Thus far in the shortened offseason, the Heat have not addressed either problem.
Not many well-known players are still available this close to the regular season, but one player, Kyrylo Fesenko, could definitely help anchor the paint.
Fesenko played for the Jazz last season and did not log many minutes, but when he did, he defended the paint quite well.
According to John Hollinger's Player Profiles on ESPN, the Jazz were 11.91 points better defensively per 100 possessions than with him on the bench.
Opposing centers had a PER of 10.4 when Fesenko was defending them.
However, the problem with Fesenko is he fouls frequently and is horrible offensively.
Of these two problems, only foul trouble would cause problems for the Heat.
They do not need Fesenko to contribute offensively with James, Wade and Bosh providing the offensive firepower. Fesenko simply needs to come in and defend.
At this point, Fesenko could be signed for at or near the league minimum.
The worst case scenario is Fesenko continues to foul too much and takes himself out of the game.
The best case scenario is the Heat bring in a center who can come in and cause problems for opposing big men becoming one of the better post defenders in the game.
All this for a fraction of the price of other premier post-defenders.
Fesenko could help the Heat shore up one of their major deficiencies from last season and do so at low cost.
