I think the only trade you need to make is secure yourself an RB2.
Yeldon is great, for now, but fournette’s return could be at any time. Maybe you can try and target the Fournette owner and swap yeldon for whoever his RB2 currently is?
Other than that, your team looks quite solid. I’m actually suprised your 1-3, looks like at LEAST a 2-2 team right now. Especially with your evidence of being the 3rd highest in scoring, it sounds like you just got unlucky a few times.
Even if you can’t swap yeldon / ridley for an RB2 somewhere, you could already be set with Ingram. Only downside is we don’t know what he looks like yet due to his suspension, but he could be just as impactful as he was last year.
Don’t panic yet bud, your squads looking good. and with an 8 team playoff, i wouldn’t stress at all.
