I like CADad's cue of keeping your back pocket going to the target longer. Get your hips going sooner and faster while maintaining your knee lift. Lead with the front hip into foot plant.
I also agree with CADad's claim that your mechanics aren't as bad as some are making it out to be. I think one key adjustment - getting your hips going and increasing your tempo/momentum - will help a lot. Getting your hips going and building up more momentum will improve a bunch of things - it will lengthen your stride, it will prevent you from opening up early, it will make up (at least somewhat) for what appears to be a lack of hip and shoulder separation, and it will get your release point further out front. You may find you lack the strength to perform these mechanics well but stick with it.
