Going thru some of the hudl highlights of the featured players on the main page, it became apparent that these kids and/or parents really need to work on putting together a good highlight reel. Hudl even gives this advice when you start to make the highlight reel. Parents/players please heed this advice because some of these highlights need some serious work. One of the players I clicked on had a highlight reel that was 18 minutes long! That's entirely too long. It should be no longer than 15 clips. Also your most impressive clip should be your first one then work your way down to the least impressive. But by far the biggest blunder everyone is making is making them WAY too long.
Hudl is a tool to help athletes but as in any tool you need to know how to use it. I've seen people use a hammer and instead of hammering the nail they hammer their fingers.
Think about your position and what college coaches are looking for from that particular position also. For example, if you're a qb, highlight you outs, post and corners as well as your home run deep balls. Highlight your decision making under pressure. If you're a reciever, obviously your great catches in various routes, but also your blocking on run plays.
