I'm not sure if you're being serious, so I'll assume you are.
First of all, Brady was not the OC at LSU. He was the "Passing game coordinator".
Lets not forget that Joe Burrow was the QB there too with the above mentioned WRs, and that team won the National Championship that year.
Somehow Brady got credit for the LSU offense and he parlayed that into being the OC for the Carolina Panthers.
But got fired after a season or two.
Brady wouldn't even be the OC here if Dorsey hadn't been fired.
