All the advice is good... particularly getting low with young players. Makes a big difference.
The one nit I will pick here is don't let anyone tell you that you should delete any of your photos. If you like them, perfect. If its a picture of the back side of your friends kid scampering down the field - and it brings back memories of the game, its a good shot. Not every shot for a personal collection needs to be a "for sale" image or a wanna-be Sports Illustrated shot. If your not shooting for anyone else other than yourself, keep what ever makes you happy. There is an over obsession on technically correct images, that often tell you absolutely nothing about a game.
Covering a game professionally is also another task completely. Peak action shots are perfectly fine... it is the nirvana of the game. But covering a game also means you have lots of b-roll shots. Line men coming out of their stance. This is particularly with little dude football. There aren't going to be a lot of really good action shots to be had. The competition just isn't that good. Maybe a half dozen opportunities in a game. You can't cover 100% of the field also. So spend time getting those story telling shots. Kids emotions. Coaches doing their thing. Parents reacting. Mini cheerleaders if they are there. Players on the sidelines not paying attention. It all paints the fuller story than a few peak action shots.
The ideal shot. Yep, face (emotion & eyes), get low, have the action clearly defined, all that mess. Want to make other parents happy... their kid, in focus, doing their thing... even if it was secondary to the main action. Centers need loving too.....
EDIT: BYW, in a lot of these shots you have the lens lower than eye level of the kid... so good on that.
EDIT 2: some of these just need to be cropped in tighter... like 0H6A9149. Good youth shot.... just crop all the extra space out of it.
You definitely get that these photos go out to the other parents and need to always include a few of the "less athletic" kiddos off to the side of the action. It makes these kids happy to see action shots of themselves even if the photos is less than stellar. The common theme is that I do need to get in tighter for those peak action shots. Weather in MT this weekends looks not so good for optimal shooting but a few more Saturdays remain to improve the shots.
