I'm sorry but talent is a major factor. You need playmakers on both sides in the NFL and don't have many/if any.
Taysom is 34 coming off a serious potential career ending if not altering injury.
Olave is our only receiver and he's coming off two concussions. He's one hit away from being out of the league.
AK is our best playmaker but he's a 30 year old RB.
Demario is old and well past his prime.
Cam is likely going to retire/ should retire.
AND our cap situation is the worse in the league.
