Erik Spoelstra's greatest challenge Monday night against the Atlanta Hawks at Philips Arena could be fielding a Miami Heat starting lineup. Already without starting center Hassan Whiteside and starting power forward James Johnson, the Heat announced Monday morning that starting shooting guard Dion Waiters is dealing with an illness and starting point guard Goran Dragic with an elbow issue, with both listed as questionable. In addition, forward Justise Winslow, who is traveling with the team after missing the past two games with a strained left knee, is listed as doubtful. Neither Whiteside nor Johnson are traveling with the team. Whiteside will miss his 10th consecutive game and 15th of the season due to a bone bruise on his left knee. Johnson, who left Saturday victory over the Los Angeles Clippers at AmericanAirlines Arena in the first quarter, underwent an MRI Sunday and was diagnosed with ankle bursitis, to be sidelined a week to 10 days.
