Every single jig will fall over, even the ones that have flat spots for the head to land on. There is no reason to worry and if you really want to see how the jig is going to perform, do the tank test but once it hits bottom count to 3 and then give it a hop and see how it falls and the way it lands, that will tell you all you need to know. I make a flipping jig that is a wedge head design, it couldn't stand up even if it was on a perfectly level surface and I don't expect it to, what it does for me is all on the fall, it falls a little different and 99 times out of 100 the fish is going to hit the jig as it falls. I thing the stand up jig is over rated, but it is because I don't dead stick a jig, plastics yes, jigs no. When the jig I'm fishing hits bottom I wait for 3 seconds and give it a small lift and drop or a shake and then bring it in for another cast, but the most important part of the presentation is the fall. When I'm using a football jig, I'm dragging it, I use heads that have a 60 degree flat eye hook so the line tie is pointing up and as I drag the jig I'm actually pulling the hook down forcing the back of the jig to periodically move up and fall down as I stop. The jig you have will work you just have to realize that the fall is more important, I even select trailers to determine the fall rate of my jig. For example if I'm fishing a 1/2oz jig around a laydown I'll probably use a beaver type jig trailer for bulk, if that doesn't produce a strike I'll change the trailer to a chunk like a strike king denny brauer or zoom super chunk, what this is going to do is make the jig appear less bulky and give it a smaller profile but it is also going to let my jig fall a little faster as the chunk doesn't create as much drag as the beaver style bait. The smaller profile and faster fall is meant to cause a reaction strike, the fish sees a smaller offering moving fast, it has to let it go or hit it and usually it hits it. So don't worry, most jigs do fall over, just concentrate on the fall and you'll catch them.
