Until now, Tim Tebow, Jet, has been a theoretical construct, a transaction and a contract and a few Photoshopped images, with thousands of fans wearing a Tebow Jet jersey but the man himself not yet having done so in public. That will end today, when, for the first time, the Jets will welcome media folk to watch organized team activities, and the world will see Tebow wearing green. No one’s wearing pads, no one’s running any real plays, and all told, it won’t tell anybody anything … except that the Tebow madness really is happening, and look — the Jets can prove it. This is happening. It begins.
