Fantasy football question

I am a big fan of fantasy football, though I know it has its detractors.
I’ve enjoyed it for years, and had a perfect championship week last year with AK rolling with 156 yards his 6 TD effort.

Unfortunately, that same weekend, Devante Adams had his incredible 11-142-3 game to beat me.

So on to this year, team Walk of Shame is looking to keep going strong.

Since I’m in ATL, I’ve got late round Marquez
Callaway in my back pocket.

Looking for a little more inside info on anyone you might have a gut feeeling will blow up and why.
As you know, these leagues are generally won not by superstars, but the bottom few on your starting lineup.
If you can find a late round diamond in the rough, it can carry you all season.
Happened to me three years ago with George Kittle, actually picked him up undrafted right before he blew up.

Thanks in advance!!
