Don't blame the losses on Atlanta. This has everything to do with Smith, Dellevadova, Shumpert, and Jones.
No team can guard James without double teaming him. It just can't be done. In the history of basketball only 3 players have taken more shots in the paint than anybody else in the league and also made the highest percentage of those shots in the league - Shaq and LeBron twice. The difference is, of course, that Shaq was not also one of the three or four best passers in the league.
Teams have a choice, either let LeBron singlehandedly destroy them, or double team him and allow someone (of their choosing) to get open looks, and pray that the person they leave open misses. Every team ever has chosen the second option. Its the right call.
If the guys being left open (in this case Smith, Dellevadova, Shumpert, and Jones) make their shots then Cleveland simply cannot be beat, not by anybody.
Check out the highlights on

LeBron has had less help in the playoffs than anybody I ever remember, but make no mistake, teams are focused on stopping him and him alone. When he gets any help at all (in the form of guys making wide open 3's) his team's cant be beat.
