Wow...reading about the Big Time Fantasy Sports (btfsports) software, you and your teams must have a great time!
The operating system requirement for the software is not spelled out, it's important to establish if it's compatible with Windows 10. I would encourage you to contact btfsports for this information before purchasing a laptop.

One last thought about laptop specifications concerns how many USB ports you will need. Please clarify what devices you will be connecting to the laptop (potential examples):
