The Detroit Lions can breathe easy heading into their bye week after putting together what looked like their most complete performance of the 2026 campaign. Their Week 5 victory over the Arizona Cardinals showed flashes of brilliance on both sides of the ball, giving Dan Campbell plenty of reasons to feel optimistic about the trajectory of his squad. However, while the team result was a positive, the individual tape revealed some concerning trends for a couple of players whose value seems to be slipping.

Wide receiver Isaac TeSlaa entered the Arizona game looking like a breakout candidate in Drew Petzing’s offensive system. After posting impressive numbers against the Jets and peaking with a career-high 95 yards in Carolina, it seemed TeSlaa had finally carved out a permanent niche in the rotation. That momentum came to an abrupt halt in the desert, where he failed to record a single catch despite being targeted twice. It was his first such disappearance since the season opener, leaving fans wondering if his recent surge was merely a fluke or if he can truly maintain consistency moving forward.

Even more precarious is the situation facing safety Christian Izien. The veteran defender has experienced a freefall down the depth chart over the last fortnight, starting with a nightmare outing against the Panthers where he surrendered a touchdown and posted an abysmal Pro Football Focus grade. The fallout from that performance became clear during the win over Arizona, as Izien didn’t see a single snap on defense throughout the entire game. While any seasoned pro can find their way back into the lineup eventually, being completely sidelined suggests that coaching staff confidence has hit an all-time low.
