The San Francisco 49ers announced on Tuesday that the team will be conducting all three open practices inside Levi's Stadium. The team has conducted their offseason workout program on the practice fields across from the stadium, which has frequently been the case. However, the team decided to mix it up for the mandatory minicamp.
Jim Tomsula was asked about this decision in his pre-practice press conference:
"Well, we went in to the stadium, number one, we'd like the stadium to feel like something old to us so we're going to practice in the stadium. We're going to take advantage of that. We'll do some more of that in camp. Just being in that stadium, working in the stadium, it's good. Obviously, the wind, the sun, those different things. Just being in our building. We'd like to make a new building an old building for us."
The 49ers will not be able to get overly used to the turf to a certain degree. It will be changed repeatedly in the coming months for various events, including their own games. They can get used to the kind of grass, but things like divets and whatnot really will not be something they can prepare for at this point.
That being said, I can't think of any negatives to getting work in at the stadium. Every little angle and issue can be addressed. Wind, sun, sight lines and so forth are things the team needs to get used to as they prepare for the coming season. It might not be a huge difference-maker, but every little bit helps.
The team was going to hold an open training camp practice in the stadium last year, but problems with the grass led to the team moving back over to the practice fields. The field was a significant problem last season, but all indications are the team is prepared for it this season. We'll see.
