How to utilize full backs properly

I think Trent Williams is the best player in football. So I spent 200K+ on a damn fullback lmao. Now I want to know how to use him properly in my run game. I don't want to do anything cheesy like fb dive every play. What are some formations or plays that either the TE or the FB clears ups some holes in the run game. Also how do I maximize honorary lineman on Williams? Thanks.

Move him to rb. You can use him to block with nearly all outside zone plays and sweeps.

With the META being 3-3-5 ...

Formations to use if you wanna use him as fullback 

Iform 

Strong

Weak

Gameplan:

Have fast WRs (with route tech if you can)

Put post up on both your OGs...

Have a good blocking TE

Have a good physical BTK RB if you arent using William's as RB

Run the ball on these 3 man fronts. Mix in playaction with your fast WR.

Realistically your opponent should have a tough time stopping this and should have to switch to a bigger defense and not the 335.

TE on drags and outs off playaction....use rb out of backfield on playaction...deep shot post should work at the right time (especially with fast WR and route tech)

I find many people like to bring up both safeties when you're running the ball...but your team has to be built for running too
