Friendly advice: Matt Prater made a career-high 31 field goals for the Lions last season, which is the third-highest total in franchise history. No. 1 and No. 2 on that list belong to Jason Hanson (34 in 1993 and 32 in 2012). Hanson was at practice Monday. He spent some time watching Prater kick, while giving what looked like some friendly input. That's two guys with a combined 711 career made field goals standing next to one another at practice. – *Tim Twentyman

Effortless: That's how running back Theo Riddick makes it look when he catches passes anywhere, but especially downfield. He made a catch Monday that was routine – for him. Riddick went over the middle and cut to his right to grab a facemask-high throw. With his arms outstretched, Riddick was able to snatch the ball out of the air before the pass could be contested by a defender, who had decent coverage. – Mike O'Hara

Off and running: The offense worked on some situations where they were backed up near their own goal line trying to find some breathing room. It didn't take long for the first-team offense to give themselves some room and much more. On the second play of the drill, a huge hole opened up between the left tackle and left guard, and running back Ameer Abdullah found it. Abdullah burst through the hole and wasn't touched until he was roughly 40 yards down the field. – Tim Twentyman

Tight end change: The Lions have eliminated the true fullback from the offense, and that means more blocking responsibilities from the tight end in a variety of sets – including playing lead blocker out of a traditional I-formation. In the competition for roster spots, blocking will have even greater emphasis in filling out depth at the position. – Mike O'Hara

Close but no cigar: If rookie cornerback Jamal Agnew was 5-foot-11 and not 5-foot-10, he might nave notched an interception Monday. Agnew was in great position to make an interception on a ball thrown from Brad Kaaya to Keshawn Martin. Agnew jumped up and got his fingers on the ball. Unfortunately, the ball still fluttered over his hands and right into Martin's hands for a completion. Oh so close. – Tim Twentyman

Play of the day – Third-year cornerback Quandre Diggs is having a pretty nice start to his training camp. He made a terrific over-the-shoulder interception on a deep ball thrown by Jake Rudock intended for Jared Abbrederis in a team drill. Diggs then became a pretty good ball carrier and was able to weave in and out of traffic to take the ball back to the 10-yard line. – Tim Twentyman
