How much FAB for a DST streamer?

I’m new to FAB. Drafted chargers for that tasty week one match up against colts. Backfire. The Pats get Dolphins this week. How much is too much FAB on a DST like Pats with a good matchup. $5?

I think that’s fine because my logic is im streaming defenses for the year and I actually bid 5 on them too- but I was outbidded 9 on them. That’s too high for me. Especially for a week and done defense…although they might be better than advertised.

I doubt it but is Dallas available? They have Washington this week and Miami next week. A little crazy stream for this week too could be San Fran.

I’m sticking with chargers this week. I have them too.
