I still remember my old, favorite football like it was yesterday. It wasn't made by Nike, Adidas or even Diadora, but it lasted me for about seven years, from when I was 7 until about 14 or so. And even though, toward the end of its life, it started to look as if it had been living in a waste dumpster, never, ever did it let me down. Despite the battle scars collected over the years, like the faux-leather gradually falling off or needing to get pumped up every time before a game, that cheap, low-tech ball always did what it was supposed to: Be, well, a ball you could have fun with. In recent years, however, things have changed quite drastically. As technology evolves, sports balls continue to get smarter and smarter, with a great amount of research and development money being spent by manufacturers. Here's where Adidas' recently announced miCoach Smart Ball comes in.
