Here’s a closer look at the draft prospects that are expected to visit the 49ers according to published reports:

Michael Floyd, Notre Dame

One of the best wide receiver prospects coming out of high school and he became productive right away, including his senior season last year when the Irish had inconsistency at quarterback. Floyd has risen sharply in the draft and is suddenly considered a top 10 prospect.

There’s even talk he could go before Oklahoma State’s Justin Blackmon. At 6-3.5, 220 pounds and with his 4.47 40-yard dash time at the combine, Floyd is bigger, taller and faster than Blackmon.

But Floyd must putg to rest his alcohol issues in interviews with teams. Floyd was cited for underage drinking twice and had a DUI. A year ago, he was suspended from the team and stripped of his role as team captain.

Floyd ended his Irish career as the school’s leader in receiving yards, receptions and touchdowns. He’s known as a tough receiver and a willing blocker with hands that engulf the ball. However, it’s curious why the 49ers are interested. Floyd is projected to be gone by the 20th selection for sure. Could the 49ers be looking to trade up?

Rueben Randle, LSU

This makes visit makes more sense. Randle is expected to be a late round option. At 6-3, 208, Randle has the size and toughness required to play in the 49ers’ offense. He has little fear treading over the middle and does have some run-after-the-catch abilities.

Randle blossomed last year with 50 catches for 908 yards and eight touchdowns, after catching only 44 passes the prior two seasons. His production is impressive considering the unstable quarterback situation at LSU with a mix and match between Jordan Jefferson and Jarrett Lee. Even with Jefferson and Lee, Randle averaged 18 yards a reception last year.

Randle failed to impress with a 4.55 40-yard dash time at the Combine and his vertical leap (31 inches) and shuttle run were among the worst for the receiver group, but he quickened his pace clocking a 4.42 at his pro day. One draft report said he adjusted his running style to notch the faster time.

What Randle will have to explain is his behavior and ineffectiveness against Alabama in the National Championship game. Many observers thought Randle quit in that game. One report said Randle has been “coddled.”

A.J. Jenkins, Illinois

Matt Barrows of the Sacramento Bee reported that Jenkins will visit. Once considered a mid- to late-round selection, Jenkins has risen lately and might be considered a second- to third-round prospect.

Jenkins was more productive at Illinois than either Floyd or Randle last season with 90 catches for 1,276 yards and eight touchdowns. One reason for his rise is his combine performance where he ran a 4.41 forty and had a 38-inch vertical leap. At 6-0, 190 he’s not as big as Floyd or Randle but is considered to be more explosive.

Even though Jenkins is a two-time Academic All-Big Ten selection, he has concentration lapses that can lead to dropped passes and poor play. Two years ago he was called for an unsportsman-like conduct penalty when he trashed talked with Northwestern fans while riding a stationary bike on the sidelines. Last season when he visited Northwestern, he caught 12 passes for 268 yards and three touchdowns. He needs to be more consistent.

Here’s a look at that game:
