邱贻可说孙颖莎的进步空间还很大（邱贻可：孙颖莎仍有巨大提升空间）
Responding to user in Chinese
It looks like I need to respond to the user's statement in Chinese. They mentioned that "Qiu Yike said Sun Yingsha still has a lot of room for improvement," which feels more like a news item than a direct question. I should inquire if they want more context, specific quotes, or a discussion about performance aspects in table tennis. There's a lot to explore regarding what "room for improvement" could mean, like serve/receive techniques or footwork, but I must avoid making up any details.
这话挺像教练的评语。通常“进步空间还很大”在乒乓里多指这些细节还有提升余地（不代表现在不好，而是还能更强）：
- 发接发与前三板：发球落点与旋转的隐蔽性、接发短球的质量与二跳控制、挑/拧后第一板的衔接稳定性
- 正反手衔接与变线：反手高强度连续厚度、正手终结的果断度；相持中直线突击与突然变节奏 
- 相持质量与失误率：高质量来回下的容错与耐心，逆旋转球、台内转台外的脚下衔接
- 关键分与节奏管理：5–5后与9–9局点的发接发选择、暂停前后的应对、被对方“黏住节奏”时的解法
- 对特定对手型的预案：内战熟人战术的二、三套方案；对左手将、异质底板、削球、发力型选手的针对性
- 体能与赛季规划：多线作战下的恢复、防伤与高强度训练的取舍；双打/混双与单打节奏切换
你是想看这句话的具体出处与原话背景，还是希望我基于最近比赛做更具体的技术/战术解读与数据对比（比如对某些对手的得分方式、关键分表现）？
