When you first look at the Chicago Bears' 2025 rookie class, it might seem like there's not much fantasy firepower to get excited about. But don't be fooled—if your league uses Individual Defensive Players (IDP) or operates in a dynasty format, there are some hidden gems worth stashing on your roster. Let's break down which Bears rookies could make a difference for your fantasy squad this season and beyond.
Dillon Thieneman (Safety): In standard redraft IDP leagues, Thieneman's value depends heavily on your league's setup. If you're starting three defensive backs in a 12- or 14-team league, he could be a low-end starter or a solid rotational reserve. Think of him ranked somewhere between 25th and 40th among safeties. If your league uses a generic DB slot, he slides closer to the 35-50 range. However, if you only start one safety or DB, Thieneman probably isn't worth a draft pick in redraft formats.
Dynasty leagues are where Thieneman truly shines. In three dynasty IDP leagues I follow, his average draft position in rookie drafts sits at 24th overall. He projects as a top-10 safety in dynasty startup drafts, and I personally rank him as the second-best rookie safety behind Ohio State's Caleb Downs. Among all IDP rookies, I have him at No. 6, trailing only Sonny Styles, David Bailey, Arvell Reese, Rueben Bain, and Downs. The key here is that Thieneman's value skyrockets in scoring systems that reward defensive backs who rack up tackles—so if your league does that, he's a must-own.
Sam Roush (Tight End): For redraft leagues, Roush has zero value right now, and even in dynasty formats, he's not someone you need to rush out and grab. The smartest play here is to let him hit the waiver wire after your rookie draft. However, keep him on your watch list: if Cole Kmet is ever traded, released, or suffers a significant injury, Roush instantly becomes a priority waiver wire pickup. For now, he projects as the team's TE3 and, as long as Kmet is healthy and on the roster, he's not going to see enough targets to be fantasy-relevant as a pass catcher.
