Top 5 impact walk-ons of BYU football's 2015 class

BYU obtained the services of some big-time talent on signing day. Players like Dayan Lake and Charles West will make an impact for the Cougars. But there are players joining BYU football without scholarships in 2015 that might have an impact as well. Here are the top prospects.

5. CB KAMEL GREENE

5-foot-11, 178 pounds
Mountain View, California

Greene is a walk-on transfer from Washington State, joining his teammate Squally Canada in the move from Pullman to Provo. Greene was an unrated prospect out of high school and walked on at Washington State with a reported 40-yard dash time of 4.48 seconds. As a high school senior, Greene tallied 77 tackles, six pass break ups, and two fumble recoveries.

Greene is a walk on at two D-I programs, so we shouldn't expect a lot from him, but BYU's secondary is always in need of athletes so if Greene can prove himself, the opportunities will be there.

4. TE JACKSON KAKA

6-foot-4, 210 pounds
Aotearoa, New Zealand
Composite Rating (out of HS): .7667 (2 stars)

KaKa is a walk-on transfer from New Mexico State. The tight end played in all 12 games for New Mexico State in 2011 before serving a mission to his native New Zealand. KaKa prepped at Kahuku High in Hawaii. He caught 15 passes for 122 yards, including one 8-yard reception against BYU.

If there is one position BYU develops walk-ons, it's at tight end (Dennis Pitta, anyone?). KaKa was talented enough to get a low-level D-I scholarship. Once he bulks up and gets in playing shape, he could be a solid rotational player for BYU's fast-paced offense.

3. QB KOY DETMER, JR.

5-foot-10, 165 pounds
Somerset, Texas
Composite Rating: .8333 (3 stars)

The son of former Colorado and NFL quarterback Koy Detmer (and nephew of BYU legend Ty) is an interesting case. He's actually very well rated, relatively, but also small. Perhaps that's how a 3-star player ends up as choosing between walking on at BYU or hometown UTSA. He is a preferred walk-on, meaning first available scholarships head his way.

But make no mistake, watch his tape and you see he knows how to sling the football. Whether he runs the scout team to perfection or ends up as a starter like Christian Stewart, Detmer will make an impact in the program and he is a great player to have in BYU blue.

2. LS MATT FOLEY

6-foot-1, 215 pounds
Temecula, California

You don't normally talk about long snappers. You normally don't rank them in a list, either. But here is where Matt Foley will get his due. Every program needs a rock-solid long snapper. When your favorite team does, you never hear their name. Matt Foley will make an impact because he practices his art and the special team unit needs him.

1. TE/LB SCOTT HUNTSMAN

6-foot-4, 225 pounds
Coppell, Texas
Composite Rating: .7826 (2 stars)

Huntsman is the high school teammate of RB signee Charles West. West is known for his blazing speed, but Huntsman kept up right behind him in Coppell's speed tests, reportedly running a 4.5 40-yard dash. He turned down scholarship offers from Purdue, Houston, Air Force, and New Mexico to accept a preferred walk-on offer for the Cougars.

He could end up playing linebacker or tight end. But his speed and athleticism will earn him a scholarship when one becomes available, and he will have his name called by announcers soon enough.
