1. Career Longevity: Although Datsyuk had an impressive career, some might argue that his time in the NHL wasn’t as lengthy as other Hall of Fame inductees. He played 14 seasons in the NHL before returning to Russia.

2. Points and Statistics: Datsyuk was known for his incredible skill and two-way play, but his career points total (918 points in 953 games) might be seen as less impressive compared to other Hall of Famers who have reached higher milestones.

3. Injury History: Datsyuk had several injury-plagued seasons, which limited his time on the ice and potentially his overall statistical output.

4. International Play: While Datsyuk had success internationally, including Olympic and World Championship play, some critics might argue that his international resume isn’t as strong as others when considering Hall of Fame credentials.

5. Playing Style: Datsyuk’s game was often about finesse, skill, and defensive play. While highly respected and admired, this style might not be as flashy or memorable to some voters as the high-scoring, offensive style of other players.

6. Team Success vs. Individual Accolades: While Datsyuk won two Stanley Cups with the Detroit Red Wings, some might argue that his individual accolades, such as Hart Trophy (MVP) consideration, were limited. He won multiple Selke Trophies as the league’s best defensive forward and Lady Byng Trophies for sportsmanship, but he never won the Hart Trophy.

7. Era of Play: Datsyuk played during an era where there were several other standout players. Some might argue that while he was among the best, he wasn’t always considered the very best player in the league during his career.

8. Post-NHL Career: Datsyuk’s decision to leave the NHL and continue his career in the KHL might be viewed unfavorably by some who prioritize an entire career spent in the NHL.

These points highlight potential reasons for disapproval, though many fans and analysts still strongly believe that Datsyuk’s overall contributions to the game warrant Hall of Fame recognition.
