Yes, all professional baseball team fields (infields} are the same size, outfields vary from stadium to stadium. This also true for high school and college baseball teams.
You would think that football is. But if you look at the whole picture they are about the same. Yeah people watch football more then baseball, but there is also baseball that people watch. But I also think that football gets a little more money because it the seats in the stadium are probably more then in baseball. But who knows. I think that they are the same.
Lots of teams share a stadium between two (or more) sports. Some teams in the same league share a stadium like the LA Galaxy and Chivas USA in the Home Depot Center.
Jets and Giants both play at MetLife Stadium.
Same as normal they just pay a bit more to have the 2 football teams name on the ball.
Celebrities support all teams in football. Some of them support the same teams their friends support. Other people support teams that represent where they are from.
No. The teams provide their own.
There are a few reasons. Some baseball teams might not be interested in sharing the same stadium with another sports team anymore in the same city like the Cleveland Indians and Browns had to do while Cleveland Municipal Stadium was still around. Another reason could be the team wants to have a new look to their stadium or even perhaps they're building a new stadium to attract a big event to their city like perhaps the Olympics or even the rights to host the All Star Game.
