Explaining blocking techniques

In basketball, "门将式封盖" refers to using both hands to block a close-range layup, similar to a soccer goalkeeper's catch; it's important to note that if the ball is in a downward trajectory or hits the backboard after the rim, it counts as goaltending. In volleyball, a block with two hands is less common but similar in spirit. In soccer, it's simply a typical goalkeeper save. I want to clarify the term and rules, and I'm excited to help! What specifics does the user want?Clarifying goaltending rules

In goaltending, if the ball is in a downward flight towards the basket or touches the backboard while above the rim, it can't be blocked. You also can’t interfere with the basket or touch the ball through the rim. The nuance comes in when thinking about if the ball hits the backboard and continues upward. In the NBA, touching the ball after it makes contact with the backboard while above the rim is goaltending, but I need to be careful not to mix up rules from different leagues.Providing blocking guidance

I want to give some general safe guidance for blocking: focus on preventing contact with the backboard by blocking the ball before it hits, and avoid making contact with the shooter’s body or swatting into the cylinder. For execution, timing, maintaining verticality, using high two-handed blocks, and keeping your chest square are key. I can also suggest counter strategies, like shielding your body, using a reverse layup, a floater, or a pump fake. If they need a specific clip, I’ll ask for a link or file.

听起来像是在说篮球里的“门将式封盖”——双手正面迎击、像守门员扑挡一样把球按下/拍掉的那种大帽。

要点简述：

• 定义：防守者双手高举、正面顶住突破或上篮，在空中把球直接“抱”住或双手拍下，视觉上像足球门将。
• 判罚风险：注意不要在球下落阶段、或球已触板且在篮筐上方时再去拍（可能判干扰球/妨碍中篮，不同联赛细则略有差异）。尽量在球仍上升、或触板前完成封盖，并保持垂直原则避免身体犯规。
• 技术要点：提前卡好位置+起跳点，双手封线（非单手追帽），胸口对齐进攻线，手腕硬、指尖压球顶端，落地收力。
• 进攻应对：身体护球/换手，反篮走底线，抛投提高出手点，或一次试探后再起跳。

你是在说某场比赛/某个回放里出现了这种封盖吗？如果有片段或具体联赛规则场景（NBA/CBA/FIBA/校队），我可以按规则细节评估是否合法、给更针对性的技战术建议。
