A very interesting game between the Arizona Cardinals and the Tennessee Titans opens the 2021 season for both teams.The contrast between Kyler Murray and Ryan Tannehill can be seen from the naked eye: the small, mobile quarterback who has a cannon for an arm, and the big quarterback who's more of a pocket passer and loves play-action situations.With both teams loaded with talent on both sides of the ball, expect this game to be close until the final minutes. This will be one of the best games of the week.QBs with the best passer rating since 2018Drew Brees - 113.0Patrick Mahomes - 109.3Russell Wilson - 107.2Ryan Tannehill - 105.9Deshaun Watson - 104.7Aaron Rodgers - 104.3Kirk Cousins - 103.6Lamar Jackson - 102.6Derek Carr - 98.6Dak Prescott - 98.6*min: 900 attempts— NFL Stats (@NFL_Stats) September 3, 2021Arizona Cardinals at Tennessee Titans injury reportArizona CardinalsThe Cardinals will start their season with no major injuries for any star player, a fantastic sign considering how much competition they'll be up against in the NFC West.
