Rob Havenstein and Bengals held Private Workout

As mentioned earlier, the Bengals could draft an offensive tackle in multiple rounds this year.

That explains why they're hosting several late-round prospects for visits as the draft inches closer. According to Aaron Wilson of the Baltimore Sun, Cincinnati has held a private workout with Wisconsin offensive tackle Rob Havenstein:

Havenstein has had private workouts for the Cincinnati Bengals, Jacksonville Jaguars, St. Louis Rams and Tampa Bay Buccaneers, according to sources.

The Mount Airy native and former all-state selection from Linganore has been projected anywhere from the third round to the fifth round by draft analysts.

The 6-foot-7, 321-pound Havenstein improved his bench press to 20 reps of 225 pounds at the Badgers' pro day workout, four more than he did at the NFL scouting combine where he had the lowest amount of the 37 offensive linemen that did the test.

He had a 5.46 in the 40-yard dash, an 8-foot broad jump and a 28 1/2 inch vertical leap.

Havenstein was a productive three-year starter at Wisconsin at right tackle, as he anchored an offensive line that led way for two of the three best single-season rushing performances in school history at 283.8 yards per game in 2013 and a school-record 320.1 yards per game in 2014

Havenstein blocked for three 1,000-yard rushers in Montee Ball, Melvin Gordon and James White, three of the top five rushers in school history. The Bengals' newfound commitment to running the ball would mesh well with an RT who started for three years in a run-heavy offense playing in a BCS conference.

Grantland actually did an interesting piece on drafting players based on production vs. promise, which Havenstein was part of. The premise of the post was why teams should look to draft players like Havenstein (production) in the latter rounds vs. guys like Florida OT D.J. Humphries (promise and potential) early in the draft.

While no one will ever mistake Havenstein for a prototypical physical specimen — his NFL.com scouting report describes his 6-7, 321-pound frame as "oafish" and "unathletic," even while commending him for trimming his weight to a level that no longer alters the tides — his role as a mainstay in Wisconsin's irrepressible rushing attack speaks for itself.

Havenstein is probably bound for the third or fourth round and for the anonymity of right tackle, as opposed to the more lucrative blindside work that awaits Humphries. But Havenstein is also bound for a long, solid pro career that will eventually make his midround pedigree look like a bargain.

It's also ironic because the Bengals appear to be interested in Humphries, not to mention he's been mocked to them in the first round of some mock drafts. Because he's projected as a left tackle, it's possible the Bengals take him in Round 1 and then Havenstein in the latter rounds to get depth and security at both tackle spots.

CBS Sports has Havenstein graded as the 12th-best OT prospect and 116th overall. He definitely looks like someone who could be either a Day 3 target, or possibly someone the Bengals could use their third-round compensatory pick on (99th overall).

Here is an excerpt from his NFL.com scouting report:

STRENGTHS: Massive tackle with very functional length. Looks oafish, but feet are much better than the eye expects. Takes quick steps and good angles for proper positioning to wall off defenders on gap plays. Above-average power in run game and runs legs to create movement. Drive blocker by nature. Block winner at point of attack.

Uses well-timed punch and has adequate foot quickness to set out to edge speed. Aggressive, play-finishing demeanor on the field. Plus body control and balance on second-level blocks with ability to sustain. Can brace against power and has feet to counter inside moves in pass pro. Shows ability to mirror and has a wide "success zone."

DRAFT PROJECTION: Round 3 or 4

BOTTOM LINE: Three-year starter who doesn't look the part in his uniform, but teams should worry more about how the dish tastes rather than how it is plated. With surprising feet to pair with good length and balance, Havenstein has the tools to be a starting right tackle in the league. He will be adequate when asked to zone block, but he can fire out and use his hips to leverage defenders out of run lanes.
