Five things to watch from the Detroit Lions rookie minicamp

The Detroit Lions begin rookie minicamp on Friday. With ten rookies to be signed from the draft and another dozen or so undrafted rookies joining the crew, it will be the first taste of real football drills since the end of the 2015 NFL playoffs. General manager Bob Quinn has set up a 90-man roster that is bound to have some enthralling positional battles. With that in mind, here are five things to look for during rookie minicamp.

1) Is Jake Rudock ready for the big leagues?

For better or for worse, Jake Rudock will be a huge storyline this offseason. The former Wolverine quarterback is already one of the most divisive figures among Lions fans. And while he won't be competing for a starting job, he could very well push Dan Orlovsky off the roster entirely if he beats him out in camp. Friday, he will take his first snaps as a professional football player.

2) Can small school players adjust to the NFL?

The Lions drafted a couple players from relatively small football programs: Miles Killebrew of Southern Utah and Antwione Williams of Georgia Southern. Both players were highlight factories in college, but the NFL is a different beast.

3) Will any undrafted free agents make the squad?

There are a few names that jump out of the UDFA list of players reportedly signed to the Lions (remember, the team has yet to confirm any of these signings). Jay Lee, a wide receiver from Baylor is one name that many analysts will be keeping an eye on. Lee hauled in 758 receiving yards and eight touchdown last season at Baylor, and many believe he has all of the physical traits to make it in the NFL. Other UDFAs to monitor include OG Chase Farris (Ohio State), TE Cole Wick (UIW) and CB Ian Wells (Ohio).

4) Will the offensive line be improved?

The Lions spent three of their first five draft picks on offensive lineman. Considering all of the Lions' troubles on the offensive line last season, this is a sound strategy. But whether Detroit spent the picks on the right players has yet to be seen. Taylor Decker, Graham Glasgow and Joe Dahl will all be under the microscope early in their careers.

5) Will the Lions hit on any late-round draft picks?

In the past few years, the Lions have been able to get some real talent late in the drafts. Last season, Detroit grabbed Quandre Diggs in the sixth round. The year before, they landed Caraun Reid in the fifth. In 2013, the Lions found Theo Riddick in the sixth round. Who, if anyone, will be the late-round steal for the Lions this year? Anthony Zettel? Antwione Williams? Dwayne Washington?
