Both Floyd and Smith come in at No. 2 among receivers and safeties, respectively, in Mel Kiper's top-five rankings by position this week. Floyd jumped Baylor's Kendall Wright for the No. 2 spot this week behind Oklahoma State's Justin Blackmon.
Alabama's Mark Barron remains the top safety.
In his weekly chat Wednesday, Kiper suggested the Chicago Bears could take Floyd with the 19th overall pick in next month's draft, adding that the former Notre Dame receiver improved his stock this past week.
Kiper also thinks Smith is a first-rounder, and he can't see the former Irish captain falling outside the first 40 picks.
With Barron not working out at the combine because of double-hernia surgery — which isn't expected to be a long-term concern — Smith took advantage of the spotlight, Scouts Inc.'s Steve Muench said:
Smith didn't have an elite workout, but he delivered exactly what you would expect from the best safety in attendance. He checked in at 6-1⅞ and an absolutely shredded 213 pounds and has long arms (32½). He's fluid for his size, flips his hips quickly, and gets in and out of his pedal naturally. Smith attacked the ball nicely, and the 4.57 he ran in the 40 is very good for a safety his size. He's a top-50 player, for sure, and there's an outside chance he could come off the board late in the first round.
