There is a place and time for everything. If there has been a solid progression starting with simple blue line shots leading to some break aways, thats fine. They are a good tool to get your timing down on closing the gap(for those who play that game) or in my case, hitting the top of my positional range and taking control of the situation. Not going to get into the deatails of it since the average player isnt quick enough to understand whats going on...lol
As a goalie I am very aware of who has and has not shot. If I have a guy who comes on the ice and takes no shoots, thinks he can just come in below game speed, deke 5 or 6 times on a slow breakaway, I ignore him. If I have a guy who has taken some shots and done his part in warming me up, I will take breakaways, 2 on 0's etc etc. If that same guy wants to also come in on some ludicrous slow breakaway attempt, I will ignore him.
I dont think any goalie worth the jock they wear worries about getting beat during warm ups. If those can shake a goalies confidence...he has bigger issues to deal with than warm ups. Many times, early in a warm up I dont even make attempts to stop some shots. I just want to visually track the shot. The eyes need warming up too. Shooting at me, play below game speed, slow shots etc etc...do no real good. Pick those corners, shoot hard and prepare your goalie. ITs a two way street.
Honestly, 99% of the yahoos who want to come in on breakaways right off the bat are the worst. They cant hit the net from the blue line with a slapper and would prob see NO breakaway in a game. Its a waste my short warm up time if I were to give them the time of day. I will give a guy one chance, take the break (IF AT GAME SPEED) and let them know I am not ready for that yet. If they try again right away, they get ignored. Dont get that hint quickly, I will ignore that shooter for the rest of warm ups.
