With second-round rookie Luther Burden III out of the picture for now at Bears training camp, there are other slot receivers doing a solid job either in his place or with backups at the same position. Despite all of the negativity regarding every Caleb Williams interception or errant throw, one surprise target almost seems to go unnoticed. While veteran slot acquisition Olamide Zaccheaus has easily caught the most passes out of that position with starters, the really stunning player has been undrafted rookie JP Richardson from Texas Christian as he works with second- or third-string players. “I think JP is a guy who has come in here and been intentional about learning the playbook,” offensive coordinator Declan Doyle said.
