2. Josh Allen, QB (Buffalo)

Drafted: First round, No. 7 overall

Allen profile: Allen has one of the strongest arms of any rookie signal caller coming into the league over the last decade. Allen completed just 56.3 percent of his passes (152-of-270) for 1,812 yards and 16 touchdowns with six interceptions. He missed the last two regular season games with an injury to his throwing shoulder. He returned for the bowl win over Central Michigan (11-of-19, 154 yards, three touchdowns, no interceptions).

How it affects Lions: Again, the Lions will have to wait and see if Allen wins the starting job in Buffalo, but this is different than the Darnold situation in New York, because the Lions don't play Buffalo until Week 15. If Allen wins the job, he should be pretty acclimated to the NFL by then.

When Lions face him: Week 15 in Buffalo

3. Roquan Smith, LB (Chicago)

Drafted: First round, No. 8 overall

Smith profile: A fast and rangy linebacker that started 15 games for the Bulldogs last year and led them with 137 tackles and 14 tackles for loss. He also chipped in 6.5 sacks.

How it affects Lions: While the Bears have a young quarterback and a lot of new faces on offense learning a new scheme under head coach Matt Nagy, it's a rather veteran group on defense that ranked in the Top 10 in just about every statistical category. Adding a player of Smith's caliber just bolsters that defense.

When Lions face him: Week 10 (Chicago) & Week 12 (Detroit)

4. Mike McGlinchey, OT (San Francisco)

Drafted: First round, No. 9 overall

McGlinchey profile: The best offensive tackle available in this draft was a two-year captain at Notre Dame playing both right and left tackle. He was part of an offensive line that paved the way for 417.6 total yards of offense per game for the Irish last season.

How it affects Lions: The 49ers allowed 43 sacks last year, the 10th most in the league. McGlinchey fits into the mix at right tackle to replace Trent Brown (now with Patriots), and could be an upgrade for the 49ers there.

When Lions face him: Week 2 in San Francisco

5. Josh Rosen, QB (Arizona)

Drafted: First round, No. 10 overall

Rosen profile: Completed 62.6 percent of his passes (283-of-452) for 3,756 yards with 26 touchdowns and 10 interceptions. He ranked second in the country averaging 341.5 passing yards per game.

How it affects Lions: The Lions could get another look at a rookie quarterback in Rosen. Counting the preseason game vs. Cleveland (Baker Mayfield), the Lions could potentially face all four of the top rookie quarterbacks in this draft class. It will be interesting to see if it's Rosen or veteran Sam Bradford facing the Lions Dec. 9.

When Lions face him: Week 14 in Arizona

6. Minkah Fitzpatrick, S (Miami)

Drafted: First round, No. 11 overall

Fitzpatrick profile: An instinctive safety at Alabama with terrific ball skills. He recorded 60 tackles last year, and led Alabama with six interceptions in 2016. He ran the 40 in 4.46 seconds at 6-foot, 204 pounds at the Combine.

How it affects Lions: He has the size and speed NFL defenses now covet because of his ability to play multiple roles and cover multiple positions. In today's hybrid and sub-package dominated defenses, Fitzpatrick is a do-it-all kind of player that can match up with both tight ends and receivers.

When Lions face him: Week 7 in Miami
