Arkansas' recruiting Class of 2015 wasn't rated as high as many others in the SEC, but it has turned out to be a very good class. It's like many recruiting classes for Bret Bielema, even from his time at Wisconsin, not rated high on paper, but produces very well on the field.

The Class of 2015 appears to be another example of that. Here's a look at five freshmen who should have a very big impact this season. They are listed alphabetically and not by order of predicted impact.

1. Austin Cantrell

It's obvious 247Sports got it right with Cantrell. 247Sports rated the Roland (Okla.) product a 4-star recruit. No other service rated him nearly that high. Hawgs247 was in attendance at one of his high school games and felt he was a man among boys. Cantrell has made a big impact early on even while battling an ankle injury. Cantrell is expected to help at tight end, fullback and H-Back. While the Hogs are struggling to find a fullback it appears Cantrell could fit that bill.

2. Hjalte Froholdt

The nose guard is splitting duties at that position and will see extensive action. Froholdt was a 4-star recruit with the 247Composite. He played at three different places in high school. He was in Ohio as a sophomore, Denmark as a junior and Florida his senior season. The moving around could have hurt many prospects, but not Froholdt. Rory Segrest and the Arkansas coaching staff is very high on him. Froholdt has a chance to be a dominant defensive lineman in the SEC before he's finished with the Razorbacks.

3. Dre Greenlaw

Once deemed a very likely candidate to redshirt by many. Instead, Greenlaw has come in and put himself in position to play a very extensive role this season at the Will Linebacker. If the Hogs struggle in the middle and Brooks Ellis moves back there then Greenlaw could even start. Greenlaw is very active and played cornerback as a sophomore at Fayetteville and then safety as a junior and senior. So he has the ability to cover backs and receivers as an outside linebacker. Was a 3-star recruit coming out of high school.

4. Ryan Pulley

Another 3-star recruit coming out of Fort Myers (Fla.) Island Coast. Robb Smith found a jewel in Florida and Pulley stands a chance to really be an outstanding cornerback at Arkansas. Pulley really looked good in the first scrimmage and in many of the open practices. Michigan State, Louisville and many others pursued him. Florida State tried to make a push at the end, but he stuck with the Hogs.

5. Rawleigh Williams III

The 3-star recruit from Dallas (Texas) Bishop Lynch led the state of Texas in rushing in 2014 with 341 attempts for 2,814 yards. With the loss of Jonathan Williams it has been well documented many times how much now the Hogs will depend on the younger Williams to help anchor the running game this season. He carried himself well in both scrimmages this fall. Says he patterns his game after former Wisconsin running back Montee Ball, who played for Bielema at Wisconsin.
