Jordan,
For scanning team radio channels, I'd recommend you start here:

Some teams can still be heard using an analogue scanner, but as stated above most are now digital. A scanner can be modified to decode these digital signals via a windows device, but it's not for the beginner. In early 2017 I would expect the first portable scanners to be released to cover the digital format used now by most teams (and marshals/officials). Expect to pay around £500 for them though.
If you are just starting with radio, I wouldn't recommend a transceiver.
