之前结合自身经历发贴普及过这个知识https://bbs.hupu.com/627611413.html，但是有两个自称踢球很多年的老手说没有这回事，说我小时候踢的飞火流星是盗版足球，正版足球没有这种变化，于是我找了一下当年职业球员对02世界杯的飞火流星的评价：

"a ridiculous kiddy's bouncing ball " Gianluigi Buffon Goal Keeper, Italy

Some people claim the new official ball exhibits the same properties as plastic inflatable balls.

Belgium's goalkeeping coach has complained the ball is "too light." Brazilian midfielder Rivaldo told reporters the ball soars too far when kicked. And Brazilian forward Edilson was quoted as saying the ball is "too big and too light."

你们可以去搜一下从02世界杯开始的历届比赛用球，基本上都有皮球越来越轻的评价

过去的比赛节奏之所以慢，球沉，球速慢是一个很重要的原因
