yeah, they're usually good, and cheaper than in recent years

I think 49ers D will be better than people expect. There will be some hiccups since they are relying on a number of rookies to contribute and the depth is definitely questionable but coaching matters. I expect Saleh will get the best out of Bosa, Warner and Lenoir.

Defense is so variable year to year and week to week, I always just look at the schedule for Week 1 and pick a vulnerable team to go against. I tried it last year with the Giants facing Darnold on the Vikings and rookie Jayden Daniels though, and it didn't work out.
