I guess soccer paid for that stadium...
but its kinda lame they would use artificial on gameday given a choice. Use the fake stuff all week for practices and I would think one football game on grass should be repairable.
It won't be a crucial time in their Tott Spurs seasons...kinda lame.
Be interesting to know who made the decision on the 'second' field surface type as it was installed specifically with NFL games in mind. So I would assume it was chosen with significant consultation with the NFL?
As for using the grass pitch, while Spurs won't play at home for at least two weeks after the Bears game - as the game precedes the international break (where national teams are playing qualification games for the European Championships) - Spurs are now a top four team in England and also for the first time in a while competing well in European competition, so it will be a key part of the season for them as it's in the midst of Champions League qualification. So I assume they would not want any damage whatsoever done by any other events simply because the sheer frequency of soccer games played by the top clubs greatly tests the durability of even the best grass surfaces.
On the flip side I think it's great that Tottenham have embraced the opportunity to stage NFL games and I think for fans and players it will be a far better experience and atmosphere than Wembley. A lot of thought has gone in to making this a multipurpose stadium, with NFL games being a major consideration. So I expect it to work well for the London games, and look forward to the Bears being the first team to use the facility
