With everyone so aflutter about the Beckham signing, I want to be on record as saying that I think Red Bull NY's signings of Claudio Reyna and Ronald Waterreus will be more influential on the field. Beckham does a couple of things astonishingly well: he delivers crosses and he takes free kicks. So he'll be good for a few highlight-reel goals, and he'll put people in the seats for a while. All of which is to the good.
Reyna and Waterreus, on the other hand, will solidify two of the most important positions on the field--goalkeeper and midfield general--for MLS' most important team. I'm going to love Beckham's occasional flashy goal, but I'm going to love RBNY's improved team play even more.
What got me started on this was a Slate article on soccer, which can be found here.
