The Cardinals went from 5-10-1 in 2019, Murray's rookie year, to 8-8 in 2020, where Murray made Pro Bowl. I expect a very competitive year from them and I would call them a contender.
Washington under Rivera has a real deal defense and that will get you places. They feature a defensive line comprised of all their 1st round picks from 2017 to 2020. They missed a combined 1 game in 2020. Their WR's, 3rd round picks in 2019 and 2020, are young but extremely productive. Their RB, another productive rookie, averaged 4.7 yards a carry. This offense is young and should be much improved this season. I believe the Football Team should be taken very seriously and they are contenders.
The Saints have lost their star and leader Drew Brees. They still have their leading rusher and receiver in Kamara. Last season nine former Saints #1 draft choices were on the roster. The team is well built and both offense and defense ranked #5. Most importantly, they still have the same Head Coach and you can count on this team to remain competitive. They are still contenders and if Doug Williams, Trent Dilfer, and Jeff Hostetler can start a Super Bowl championship team, so can Jamies Winston. Again, this team has the coach who can make this happen
