Not much to disagree with here, only on the margins. As usual a thoughtful reply:I'm going to disagree with you a bit here. While goalkeeping is a little more precise than playing in the field, there are no absolutes in soccer. Like the overcoaching article mentions, coaches need to avoid using terms like "always" and "never". Soccer is the most situational sport with multiple variables you have to assess in a split second. Falling back to the 6 may have been the appropriate decision in your son's circumstance, but never sliding feet first would be taking a very valuable tool out of a keeper's tool box. It's effective, albeit with risk. Personally, I haven't seen it result in as many red cards as you have experienced. These risk/return equations are all things that a soccer player needs to understand to develop their soccer IQ. One of my pet peeve's is seeing a goalie rush out to stop a 1v1 and suddenly stop and backpedal in retreat. That typically doesn't end well as you've released much of the pressure on the attacker and are likely off-balance as you backpedal. Even if you've made the wrong decision to charge the attacker, you're only going to compound the problem by retreating.
-You don't go feet first in the box because it is much more effective to block, starfish, slide/smother, do the crucifix, do the Crazy Ivan, or do a sliding davis than feet first. There's just so many more effective techniques (and the one that's the right answer more than 1/3 of the time is actually the hold) than sliding with your feet that it is almost never the best answer and something the youngers and untrained really tend to do. Sliding feet first is reserved 100% for out of the box and then, as you say, subject to the risk/return equation (and the proper way to execute it anyways is more like a swinging gate than a studs up feet forward slide which even if it makes contact with the ball is technically a red card offense). I agree 100% on once you make a decision, whether in goal or on the field, you have to go with it, "usually".
-There are some absolutes in soccer. You should "always" be aware of your surroundings and cognizant of the potential play making passes. You should "always" be ready to receive the ball on offense, regardless of your position on the field. You should "always" if defending switch to a defensive mode if the team has lost the ball. You should "never" lose sight of your positional reference on the field. You should "never" lose sight of the potential pass opportunities around you. You should "never" jump on a throw in and give it away due to a technical foul. I agree one problem is that many "usually" are interpreted to always such as never toe poke the ball on a shot.
