The Bears made their first big move of a franchise-defining offseason Tuesday when they officially announced Shane Waldron as their new offensive coordinator. In Waldron, the Bears get a bright, creative play-caller with deep roots in the Shanahan tree. Waldron has spent the last three seasons as the offensive coordinator for the Seattle Seahawks. He arrives in Chicago with play-calling experience, a track record of maximizing his personnel, and a proven ability to dial up explosive plays. Waldron’s arrival doesn’t tip the Bears’ hand about their pending quarterback decision, but Waldron will play a significant role in keeping Justin Fields or drafting Caleb Williams.
