Just a thought, the new practice facility that was finished over the summer is turf. I understand the sentiment of playing on grass, but wouldn't it be best for the team to play on what they practicing on?
Also, the Tampa Sports Authority (who operates RJS) spends north of $1,000,000 on grass each year. I know circumstances are a bit different because the NFL's grass requirements can be a bit stringent (for starters, between the hashes and endzone is replaced pretty much after every game) and RJS hosts a lot of different types of events that require grass being removed and reinstalled (i.e. monster jam for example). But turf could be more cost effective. According to an AB survey, schools with grass football fields average roughly $57,000 in annual maintenance costs, whereas schools with synthetic turf in their stadiums spend about $16,000. Multiply that over 20 years, and that's almost $1,000,000 in savings.
