Davids is 34 on his next birthday (March), hardly sustainable for the MLS to start signing "big-name" players that cost a bomb and who are only there for a paid retirement. Why does each generation try to sell soccer to a populace who don't really want it - as a whole. I refer you to the NASL - exact same mistakes were made, albeit the MLS LOOKS to have a little more protection in Beckhams contract, but thats based on media speculation.
