The Philadelphia 76ers have gotten off to a rough 0-3 start this season. Their latest loss came against the rebuilding San Antonio Spurs at home. The Sixers entered this season with championship aspirations, but their poor start has left fans and critics questioning their mettle.The first two games were against heavyweights like the Boston Celtics and Milwaukee Bucks, so those defeats didn't raise many eyebrows. However, the Spurs are projected to be a lottery team. Losing to them at home and at full strength brought the critics alive.Joel Embiid struggled in the first two games but returned to form against the Spurs, scoring 40 points on 14-of-25 shooting. However, his co-star James Harden had the opposite fate. After dropping 30+ points in his previous two outings, "The Beard" could contribute only 12 points on a 4-of-18 shooting against San Antonio.The Philadelphia 76ers got ahead by six points at the end of the first quarter but were outperformed by Greg Popovic's team throughout the rest of the game. NBA Twitter didn't miss the opportunity to mock the 76ers for their surprising 0-3 start.One fan wrote:"James Harden thinking about bringing back the fat suit if the Sixers continue losing"Another added:"You know Ben Simmons is itching to tweet something about the winless 0-3 Sixers lol"Here are some more reactions:NBA Memes@NBAMemesJames Harden (12 points, 4-18 FG) against the tanking Spurs1257140James Harden (12 points, 4-18 FG) against the tanking Spurshttps://t.co/9WVDV3KBI5NBA Memes@NBAMemesJoel Embiid (40 points) looking at James Harden (12 points) after losing to the Spurs72947Joel Embiid (40 points) looking at James Harden (12 points) after losing to the Spurs https://t.co/LX1By4H5h0Tommy Beer@TommyBeerYou know Ben Simmons is itching to tweet something about the winless 0-3 Sixers lol431You know Ben Simmons is itching to tweet something about the winless 0-3 Sixers lolJohn Hollinger@johnhollingerSixers are so lucky the Phillies play tonight526Sixers are so lucky the Phillies play tonightNBA Memes@NBAMemesJames Harden thinking about bringing back the fat suit if the Sixers continue losing2866270James Harden thinking about bringing back the fat suit if the Sixers continue losing https://t.co/DGzVgJRpNHNBA Memes@NBAMemesThe Sixers have not won since Doc Rivers went on a thirst trip on Twitter.46323The Sixers have not won since Doc Rivers went on a thirst trip on Twitter. https://t.co/rdjwLkwDnhAhmed/The Ears🇸🇴@big_business_I get it brother, Sixers look like a 2 pack of ass I'm sick twitter.com/alexwinton_/st…Alex@alexwinton_@big_business_ Tryna talk about my PG without context, had to get my jab in 131@big_business_ Tryna talk about my PG without context, had to get my jab in 😂😂I get it brother, Sixers look like a 2 pack of ass I'm sick twitter.com/alexwinton_/st…buckets@bucketseagles, phillies & sixers9520eagles, phillies & sixers https://t.co/83IsO9sgDsbuckets@bucketsphiladelphia sports fans to the sixers since the phillies are cooking right now:263philadelphia sports fans to the sixers since the phillies are cooking right now: https://t.co/K0xnLZdhwsNBA Memes@NBAMemesSixers fans realizing their team's true vision after going 0-32209189Sixers fans realizing their team's true vision after going 0-3 https://t.co/djJS0ReZAtbuckets@bucketssixers so far this season:457sixers so far this season: https://t.co/56eujJ1G4RJeff McDonald@JMcDonald_SAENThe Sixers didn't get the Adam Silver memo. twitter.com/mikefinger/sta…Mike Finger@mikefingerMeanwhile your tankin’ local cagers, trying to go 2-1, are pulling away from the title-contendin’ Sixers, about to go 0-3.191Meanwhile your tankin’ local cagers, trying to go 2-1, are pulling away from the title-contendin’ Sixers, about to go 0-3.The Sixers didn't get the Adam Silver memo. twitter.com/mikefinger/sta…2K-COMBAT TV@2kCombat@BleacherReport Doc Rivers if the 08 Celtics didn't exist47429@BleacherReport Doc Rivers if the 08 Celtics didn't exist https://t.co/NErw2epLsaBarstool Sports@barstoolsportsBen Simmons watching Joel Embiid and The Sixers start 0-3105972Ben Simmons watching Joel Embiid and The Sixers start 0-3 https://t.co/C77ZdPBIcTNBA on TNT@NBAonTNTSixers fans after 0-3 start 🙃788112Sixers fans after 0-3 start 🙃 https://t.co/456zD9aqSRAustin Krell@NBAKrellThere was not enough power to give the Sixers and Phillies wins, so the Sixers sunk for the Phillies to swim.472There was not enough power to give the Sixers and Phillies wins, so the Sixers sunk for the Phillies to swim.Doc Rivers believes Philadelphia 76ers are not ready to win yetPhiladelphia 76ers coach Doc Rivers had a simple answer about the team's woeful start following their loss to the San Antonio Spurs. Rivers believes the new-look Sixers aren't "ready to win yet."Rich Hofmann@rich_hofmannDoc Rivers: "I've been through these and we're not ready yet honestly, we're just not. We're not ready to win yet. You can feel that and so we got a lot of work to do."194Doc Rivers: "I've been through these and we're not ready yet honestly, we're just not. We're not ready to win yet. You can feel that and so we got a lot of work to do."James Harden is entering the season healthy. His style of play has been different thus far, something Joel Embiid and the rest of the players may have to adjust to as the season progresses. Unlike last season, Harden has looked aggressive in his scoring approach. Hence, he may not be able to facilitate plays consistently.The Philadelphia 76ers need to improve their overall play on offense and get everyone involved. The ball movement hasn't been there to create better scoring opportunities. They tend to rely on Embiid and Harden to score on isolation plays, which hasn't proved to be a successful ingredient in their first three games of the season.Nevertheless, considering the talent at their disposal, the Sixers will likely resolve their woes offensively. However, their defense may need a lot of work. The Sixers just haven't looked sharp with their defensive schemes. Across their first three games, the Sixers have allowed their opponents to score 48% from the field and 35% from 3-point range.The Philadelphia 76ers still have a long road ahead, so facing these issues now is ideal for them to find solutions and get back on track. They still boast one of the deepest and most versatile rosters. Even if their 0-3 start seems alarming, it wouldn't be a surprise to see them bounce back.
