For three Heat players who are hardly finished products, varying challenges accompanied them to the start of training camp Tuesday in Boca Raton.
For Justise Winslow, there’s the looming deadline on a contract extension.
For Josh Richardson, there’s the challenge of taking his offensive game to the elite level that his defensive game has reached.
And for Tyler Johnson, there’s the burden of greater expectations after a salary spike from $5.8 million the past two seasons to $19.2 million each of the next two as part of a backloaded contract that was initially offered by the Brooklyn Nets and matched by the Heat.
