A slot receiver is a great way to make a team more versatile. They are a great option for teams with a tight budget, and they’re usually quite fast, so they can make quick plays that might otherwise be difficult for other receivers to pull off. They’re also a great option for teams that are using a spread offense, because they can help take the pressure off the quarterback.
