1. San Francisco 49ers

Every team needs to be healthy for a Super Bowl run, but this team really needs to stay healthy for that to happen.

2. Seattle Seahawks

Even with a little offseason drama involving QB Russell Wilson, they seemed to have brushed that off and are going back to work like it never happened.

3. Los Angeles Rams

They went big and sent off two future 1st round picks along with QB Jared Goff to get QB Matthew Stafford from Detroit. Now the onus is on head coach Sean McVay even more to recreate what they had not too long ago for a Super Bowl run.

4. Arizona Cardinals

If Arizona has a repeat of what happened in the second half of last season, head coach Kliff Kingsbury will be looking for a new job.
