Detroit Lions mock draft roundup: After first wave of free agency

Jeff Risdon, Lions Wire, Connor Rogers, NBC Sports: Zach Frazier, IOL, West Virginia

Within the same vein that Barton looks like a fit for the Lions, being an option at left guard right away and a contingency plan for Ragnow possibly retiring within the next few years, Risdon has them taking Frazier. Rogers hit the same notes.

Will Helms, Pro Football Network, Joel Klatt, Fox Sports: Kool-Aid McKinstry, CB, Alabama

Helms feels like the Lions haven't addressed the secondary "like I think it should" so far in free agency, which pushed his choice of McKinstry at pick No. 29. The Alabama product is lined up to be a first-round pick in a deep cornerback class, but a foot injury discovered at the NFL Combine might drop him to later than initially expected.

Kyle Dvorchak, NBC Sports: Kamari Lassiter, CB, Georgia

Dvorchak didn't go the same way as Helms to say the Lions haven't done enough to address their secondary in free agency, but he did cite how the addition of Carlton Davis would allow Lassiter to develop as the CB2 during his rookie season.

Joe DeLeone, SI.com: Jer'Zhan Netwon, DT, Illinois

The signing of DJ Reader seems to drop defensive tackle down the Lions' draft board, and out of the first round. But DeLeone noted the culture fit for Newton with Dan Campbell in Detroit, and his quote describing his meeting with the Lions at the combine may have only clinched it.

Tony Catalina, Pro Football Network: Byron Murphy, DT, Texas

We had Murphy to the Lions in our pre-free agency mock, and it made a ton of sense then (should be available). Catalina remains in that well here, in what would seem to be a "best player available" scenario.

Charlie Campbell, Walter Football: Jackson Powers-Johnson, C, Oregon

Another interior offensive lineman here, with the same ideas (replacing Jonah Jackson at left guard immediately, possibly replacing Frank Ragnow retiring soon?). The big question here, when the draft actually comes, is if Powers-Johnson is gone well before pick No. 29.
