Can anyone tell me about these Lego-compatible figures? They clearly aren't Lego brand, they don't look like Mega Blok figures or Tyco figures that I have seen (not that they couldn't be one of those brands potentially). They have no brand markings on them anywhere that I've found, but they can attach to standard Lego bricks. (bonus: how valuable are they? not very?) edit: some of the football characters (but not the coaches/plain people) have levers on their back and one locking leg.
My first guess is that these are early generation Oyo Sportstoys (http://www.oyosports.com). The legs on the current version of Oyo figures are different (they have an articulated foot) but perhaps there was an earlier iteration of them that looks like the ones you have?
