His timed drills might not pop, but on the field he was comfortable and improved his stock.Oregon tight end Terrance Ferguson participates in drills during the 2025 NFL Combine at Lucas Oil Stadium. / Kirby Lee-Imagn ImagesTight end is an under-the-radar need for Dallas. They have several intriguing players behind starter Jake Ferguson, but none have proven they can be counted on full-time. Even Ferguson had his share of struggles in 2024.That’s why the Cowboys were likely paying attention to the group on Friday, which means they saw Terrance Ferguson show out.
