Think about that Longley, Wennington, and Kleine, not exactly hall of famers. Not of them elite defenders, or offensive players.
Right, now we have Kanter, Theis and Willliams, do you think that these guys are equal to the above three?
Kanter has proven time and time again that he can't be relied upon in the playoffs.
Utah and OKC will tell you Kanter is horrible on defense.
Portland was the latest to experience Kanter's horrible D against GSW.
Steph Curry annihilated the Blazers because Kanter wouldn't come out and defend Steph in the pick and roll.
Theis and RWill are just 6-8 players.
Both of them can't guard Embiid in a best of seven series.
Longley, Wennington, and Kleine are not close to being elite but they are big, they play physical, and they're 7-footers.
In the first game against the Sixers, the Celts got outrebounded 62-41.
Against the Knicks, the Celts allowed the Knicks to get 16 offensive rebounds.
Clearly the Celts have a big man problem.
