We chose this for our youth football organization to help prevent holding the player's hands to the line for them to go where they have to go. There are a few things that would make this product much better:1. Smaller position markers (larger players can line up on point with the T, G, or E)2. add-ons to show gaps (1, 2, 3, 4 holes - etc) and defensive alignments - another benefit with narrower markers.These markers are high quality and much heavier than I imagined, great for durability but can get old carrying it to the field on a regular basis. However, even with the weight a good wind gust (20+mph will flip it). I do highly recommend this for others.
