Pro days are up and running all over football nation, but the coming days will feature some players on the Broncos' to-do list.

Already, Wisconsin running back Montee Ball gave the league's personnel evaluators plenty to think about Wednesday with his quality work in Madison. On Friday, the Buckeyes will go to work in Columbus, Ohio.

There, defensive tackle Johnathan Hankins, at 6-foot-3, 320 pounds, has the build the Broncos want on the inside of the defensive line.

At times, Hankins flashes upper-tier skills, but he is is a player who makes some scouts nervous because they feel like he had "bad weight" during the season and doesn't always play to his substantial talent.

But plenty of teams have a first-round grade on him because of his quick feet in tight spaces.

At 6-1, 257 pounds, John Simon played defensive end for the Buckeyes, but the Big Ten's Defensive Player of the Year this past season has said he would move to linebacker in the NFL if teams wanted him to. He had shoulder surgery last month so may not put in a full workout.

Also, Buckeyes' tackle Reid Fragel (6-7½, 308 pounds) is worth a long look. A big-framed player with good power in his game and quick enough feet that he was a tight end when he arrived in Columbus.

Prospects at Texas A&M will also work Friday, including running back Christine Michael, who just might be the most explosive athlete among the big backs on the board (4.54 40 at 220 pounds to go with 43-inch vertical jump). But he does carry some questions about injuries — torn ACL and fractured leg over the course of his career — and attitude.

Tuesday, Loveland's Collin Klein is expected to throw for scouts in Manhattan, Kan. He needs to show good timing, good anticipation and some zip on the ball to keep himself in draft discussions.

Running back Johnathan Franklin, who finished his career as UCLA's leading rusher and 19 100-yard gamers, will work out Tuesday in L.A. as well.

Florida also goes to work Tuesday for what will be a packed house to see defensive tackle Sharrif Floyd, who is now considered the top interior defensive linemen on the board by many in the league.

He'll be long gone by the time the Broncos pick on the draft weekend, but they could certainly take a long look at linebacker Jon Bostic. Bostic is 6-1, 245 pounds and may have been the most consistent player in the Gators defense this past season.

Gators safety Matt Elam will be another player of interest for the local franchise as well.

And Wednesday, don't try to get a rental car in Tuscaloosa, Ala., as the league will gather for the Crimson Tide's pro day. Cornerback Dee Milliner, linebacker Nico Johnson and defensive tackle Jesse Williams, who've all had some kind of surgery since the season's end, are of particular interest to the Broncos.

Milliner worked out at the combine and the Broncos would need a draft-day plunge to have a chance at him but due diligence is always required. Johnson and Williams did not work out at the combine.

The Broncos will also take a long look at Tide tackle D.J. Fluker and center Barrett Jones too.

Michigan State, with running back Le'Veon Bell, will go that day as well as will Washington, where the Broncos will be one of many teams with a keen interest in cornerback Desmond Trufant.

Locally, the Colorado and Colorado State will also work Wednesday. At CSU, tackle Joe Caprioglio, who has worked out in suburban Denver with trainer Loren Landow, will have a chance to show what he has to offer while CSU-Pueblo tackle Ryan Jensen, who may have been one of the highest-graded players not at the scouting combine, is expected to work out with the Rams as well.

At CU, tackle David Bahktiari, who some teams see as a guard in the NFL, could still help himself significantly as could defensive linemen Will Pericak. Pericak turned some heads with good work at the East-West Game in January and was not at the combine so this will be many scouts' first in-person look at him since.

Buffs tight end Nick Kasa, with another strong day, could continue to power his way up the rankings at his position, especially if he catches the ball well in drills.
