Detroit Lions
The obvious questions are "How will the team move on from losing both coordinators?" and "How will the defense bounce back from all those injuries last year?" Those have already been touched on here and here, respectively, so let's take a look at two other queries:
Will the new-look O-Line keep Jared Goff upright?
Last year's core offensive line consisted of Taylor Decker, Graham Glasgow, Frank Ragnow, Kevin Zeitler, and Penei Sewell. This offseason, though, Ragnow retired and Zeitler left for the Titans, leaving some huge holes in the center of the line. So far, Detroit seems to have settled on shifting Glasgow to center.
On his left side, Christian Mahogany, in his 2nd year, is penciled in to start, and on his right, he'll see 2nd round rookie Tate Ratledge, mullet and all.
The newcomers' task? Keep that pressure from coming right into Goff's face. The last few years have done much to improve his confidence and resilience, and the sheer amount of work the team did to build up the offensive line as soon as he was traded to Detroit takes much of the credit for that. This is a team that lives and dies depending on how well they do in the trenches, so this group absolutely must step up for Goff and the rest of the offense to continue to succeed.
Does Terrion Arnold take that huge step forward?
Cornerback is one of the most difficult positions to make the adjustment from college to the pros. For almost anyone not named Sauce Gardner, the general wisdom is that it takes around a full year to truly figure out the game at the NFL level. For a secondary that has been rightfully much maligned for most of the last several years, Arnold proving his worth and becoming a true lockdown corner would be a game-changer.
Last year, in his rookie season, he was credited for ten passes defended, according to PFR. On the flip side, he was also penalized quite a few times, especially early in the season, for how handsy he was against opposing receivers. To his credit, he began cleaning that up around mid-season, and now looks to make a hoped-for jump in performance in his second year with Detroit. He'll have veteran DJ Reed to help mentor him this year, and with one of the best safety tandems in the league in Kerby Joseph & Brian Branch also on the field, he'll be in a much better position to grow into his role.
