Here’s this week’s college football viewing guide as we search for the top prospects in the 2015 NFL Draft:

OLB Eric Striker, Oklahoma

Opponent: Tulsa
Location: Skelly Field at H.A. Chapman Stadium in Tulsa, Okla.
Kickoff: 11 a.m. CT
TV: ESPN2

Something tells me the Bears will be looking for a linebacker early in the 2015 draft. So while the Big Ten plays every midwestern directional school possible at 11 a.m. Saturday, turn on ESPN2 and check out Oklahoma outside linebacker Eric Striker, who racked up seven solo tackles and forced a fumble against Alabama in the Sugar Bowl last January. Striker is still a junior, but he could very well play his way into the first round of the draft next spring.

DE Leonard Williams, USC

Opponent: Stanford
Location: Stanford Stadium in Stanford, Calif.
Kickoff: 2:30 p.m. CT
TV: ABC

Williams is coming off a shoulder injury suffered in 2013, but the junior could very well be the first defensive lineman taken in the draft next year. At 6-5, 298 pounds, Williams has the size and speed to make it at the next level. Saturday will be a prime opportunity to put together some impressive tape as he’ll face Stanford left tackle Andrus Peat, a massive 6-7, 312 pound tackle who could also be a Top 10 talent.

QB Marcus Mariota, Oregon

Opponent: Michigan State
Location: Autzen Stadium in Eugene, Ore.
Kickoff: 5:30 p.m. CT
TV: FOX

Mariota likely would have been a first round draft pick last year, but now he has a chance to make himself the No. 1 overall pick in 2015. Michigan State might be the toughest defense he’ll see all season long, so this is a great chance for him to shine in a big game. Spartans defense end Shilique Calhoun and free safety Kurtis Drummond are two NFL prospects on the other side of the ball who will test Mariota.

WR Devin Funchess, Michigan

Opponent: Notre Dame
Location: Notre Dame Stadium in South Bend, Ind.
Kickoff: 6:30 p.m. CT
TV: NBC

Funchess is making the move from tight end to wide receiver, which should have scouts drooling considering the way 6-5, 230 pound targets are being plugged into NFL offenses these days. Funchess was probably a second round talent as a tight end, but he could move his way up with a productive season at wide receiver.

S Kyshoen Jarrett, Virginia Tech

Opponent: Ohio State
Location: Ohio Stadium in Columbus, Ohio
Kickoff: 7 p.m. CT
TV: ESPN

Jarrett is a little small at 5-11, 192 pounds, but he stretches the field and is a playmaker. He’s a versatile safety who can play strong or free. He has good speed in coverage, but is also a stout run defender. Ohio State’s offense wasn’t very impressive last week against Navy so Jarrett and the Hokies’ defense could make a big statement on the road in Columbus.
