Shazier has been widely projected as a first-round pick and the Steelers would be looking at the former Buckeyes star as an inside linebacker.
Shazier recorded 101 tackles in 2013, the third-highest single-season total in Ohio State history, and the 6-foot-1, 237-pounder has excellent speed.
The Steelers will almost certainly get only one crack at Shazier, as he shouldn’t get drafted any later than the early part of the second round.
“You could make an argument he’s one of the 10 best football players in this draft based on being a pure, instinctive football player,” ESPN NFL draft analyst Mel Kiper Jr. said of Shazier.
Zumwalt also projects as an inside linebacker in a 3-4 scheme, and the former UCLA star is expected to get drafted in the third or fourth round. The 6-4, 235-pound Zumwalt recorded 91 tackles last season and intercepted a pair of passes.
Bucannon is one of the top safeties in the draft and is in the tier of players at the position after Alabama’s Ha Ha Clinton-Dix and Louisville’s Calvin Pryor.
The 6-1, 211-pounder had 15 career interceptions at Washington State, including six last season when he also recorded 78 tackles and forced three fumbles. Bucannon could get drafted as high as the second round.
This is the first day that the Steelers are hosting draft prospects since Monday.
General manager Kevin Colbert and coach Mike Tomlin each attended pro days at Penn State and LSU the previous two days.
The Steelers are allowed to host 30 prospects for pre-draft visits and they have met with two linebackers and two safeties this week.
Pryor, a projected first-round pick, visited the Steelers on Monday.
