While the Los Angeles Bureau of Engineering moves ahead with its competition for a $350 million renovation and expansion of the Los Angeles Convention Center, the NFL is threatening to make those plans obsolete. According to NBC Sports, a league source has confirmed that the NFL will send one or even two teams back to LA within the next one to two years. Two favorites include the St. Louis Rams and the Oakland Raiders. If the NFL comes to town then AEG's plans for a new downtown stadium (by Gensler) and convention center expansion (by Populous) may follow. Of course a team could just as easily move to a site being floated near Hollywood Park, in Chavez Ravine, and in City of Industry. As of now the city has shortlisted AC Martin/LMN, Gensler/Lehrer Architects, and HMC/Populous for the convention center. No word from the Bureau of Engineering at this point. Stay tuned as we try to make sense of all this.
