Snap observations: Glasgow, Bademosi get long look

Detroit — Detroit Lions coach Jim Caldwell called them pre-planned rotations, but how much did rookie Graham Glasgow and veteran cornerback Johnson Bademosi see the field, subbing in for starters Laken Tomlinson and Nevin Lawson in the win over the Philadelphia Eagles? Quite a bit, actually.

Glasgow, making his debut on offense, took over for Tomlinson in the first quarter and maintained the left guard job until the final frame, out-snapping the starter, 34-27.

Tomlinson, a first-round draft pick in 2015, has been the weak link on the offensive line this year. Glasgow, who many expected to challenge Travis Swanson for a starting center role this year, was a third-round draft pick this year.

At cornerback, the rotation between Bademosi and Lawson made more sense, given Lawson was battling an illness during the week. Lawson still played the bigger role, but the margin was slim, 31 snaps to 24. Even though it's one game, it will have Bademosi more prepared to step in if there's a future injury situation.

It's worth monitoring both rotations going forward, to see if they are temporary, or the first signs of permanent lineup changes.

Here are some additional observations from the snap count report:

• Rookie safety Miles Killebrew, primarily working as the fifth defensive back in dime packages, played a career-high 21 snaps. Fellow rookie Antwione Williams went in the opposite direction this game. After starting in place of DeAndre Levy last week, Williams played just two snaps against the Eagles, ceding his playing time to Thurston Armbrister.

• In their Lions debuts, tight end Clay Harbor played 23 snaps, while defensive end Armonty Bryant was on the field for 19 defensive plays. Rookie linebacker Steven Longa was one of the team's top special teams contributors, playing 15 snaps with those groups.

• Even with better defensive line depth with the addition of Bryant, edge rusher Kerry Hyder barely left the field, playing 53 of the 60 snaps.

• Serving as part of the tight end rotation with Eric Ebron out with an injury, offensive tackle Corey Robinson worked a career-high 19 snaps.

• As expected, Theo Riddick dominated the backfield rotation, nearly doubling Zach Zenner's workload, 40 to 21 snaps.
