鱼缸论是事实，但西甲强度低也是事实（鱼缸论成立，西甲强度偏低亦属实）

Discussing football competitiveness

I'm thinking we should focus on providing factual context to avoid heated fan debates in football. It's important to present metrics on balance versus dominance, include details about schedules, playing styles, and refereeing aspects like win margins and expected goal differences too. I could mention the "fishbowl theory." I won't delve into coding, rather aiming for a simple analysis with 4-6 bullet points covering key metrics and relevant timelines for leagues. Lastly, I’ll suggest important data points like UEFA coefficients and UCL results.Summarizing league dynamics

I’m concluding that both statements about football leagues partially hold, but it's essential to distinguish between "league depth" and "top-end strength" as well as stylistic familiarity, or the "fishbowl" concept. It's important to note that this idea is hard to validate without player movements between leagues. We have examples of players adapting, so it’s not totally unfounded. I’ll keep my response concise, with clear stats about European trophies won by La Liga clubs and recent Champions League winners through 2024.Analyzing league strength

When considering the strength of leagues, we need to specify the dimensions we mean: overall league depth versus the competitive intensity of mid and lower tables, including factors like ball possession and pace. Claims of "low strength" aren't strongly supported, especially with La Liga's continued success in the UEFA Europa League. I can suggest objective indicators like the UEFA five-year coefficient and market values from Transfermarkt to clarify standings, noting that historically La Liga ranks high but has competition from leagues like the Premier League and Serie A.Defining strength in football

"强度" refers to various aspects like tempo, pressing, and physicality — for instance, how much distance players cover and sprints made during matches, which suggests that the Premier League has a faster pace. The "fishbowl theory" holds some truth, as context does matter for players. A better phrasing might be that La Liga's top-end strength is high, while its league depth and competitive pace are lower compared to the Premier League. I can present a structured response in Chinese with bullet points defining strength, analyzing the fishbowl theory, and suggesting final thoughts.
