The offseason between 2019 and the 2020 NASCAR Cup Series campaigns did not feature much activity in the form of drivers switching in and out of the top racing teams.
However, out of all the 17 drivers who raced for Joe Gibbs Racing, Stewart-Haas Racing, Hendrick Motorsports, Team Penske or Chip Ganassi Racing in the 2019 campaign, 16 returned to the same racing teams for the 2020 campaign.
The only movement that took place was at Stewart-Haas Racing, indeed they have changed their driver lineup for the last four campaigns now.
Stewart-Haas Racing had replaced Daniel Suarez, who later agreed to sign with Gaunt Brothers Racing, with rookie Cole Custer, who spent the last three campaigns competing for the Stewart-Haas Racing Xfinity Series team.
Nonetheless, there could be a lot more driver movement between these five teams from the 2020 and 2021 campaigns, with only nine of these 17 drivers are under contract for the 2021 campaign. Only one of these nine drivers signed a new deal after the 2020 season begun.
