Agree with LLB. However, you may be limited by the amount of grain based on your setup. While this generalality applies to using a mash tun as well, I bet it's a lot more common to be limited when you do BIAB.
Determine how much grain your setup can handle. If a recipe goes over this, you'll need to switch over to partial mash. In my case, I'm limited to about 8 lbs of grain before my kettle is too full to manage easily. Any higher gravity brews require me to go partial mash.
Cheers.
