Everyone on this site knows the Lions' needs, so I'm not going to waste time going over them. Now, there are 3 prospects from the Pac-12 that I think will not only fill those needs, but also provide great value if the Lions can get them where I have them slotted here. The prospects are:
Datone Jones, DE, UCLA (Round 2)
Unless the Lions spend the 5th pick on Jones, this is the only time they can hope to get him. Jones has a low first round grade but many think he could be the most underrated talent in the draft. He's big (6'4", 283 lbs.), quick (his 4.3 20-yard shuttle was tops among defensive linemen at the Combine) and productive (19 tackles for loss and 6.5 sacks last year). He's a space-eater who can get to the quarterback by either using his quickness to get around a lineman or plowing over him with his bull rush. He consistently beat consensus top-5 pick Eric Fisher in the Senior Bowl (he was the only one who could).
Robert Woods, WR, USC (Round 3)
Robert Woods is a burner who could be the most NFL-ready skill position player in this year's draft. He's 6'1", 190 lbs. and has fantastic speed. He's as good of a route-runner as you'll find in the draft and isn't afraid to lay out for balls or go over the middle. He has big, reliable hands and solid leaping ability. He could stand to bulk up some and get to a solid 200 lbs. to avoid injury.
Kenjon Barner, RB, Oregon (Round 4) *hopeful compensatory pick for Eric Wright*
Barner is exactly what the Lions need in the backfield: a shifty running back with excellent speed and play-making ability. Barner is an explosive back with fantastic hands. In my eyes, he's the draft's top option to replace what Jahvid Best did for the Lions. He's small (5'10", 195 lbs.) but has showed NFL scouts a willingness to block (even though he'll probably never be asked to pass-block in the Lions' offense). That said, he (like Woods) could stand to gain a few pounds to avoid injury.
There are two things that all 3 of these guys have in common that the Lions desperately need: leadership and intelligence. All 3 earned a 3.0 GPA or higher in college and have fantastic football intelligence. Jones was a vocal leader on UCLA's defense and showed up to every Combine interview in a suit (everyone else was in workout clothes) because he wanted to be "the best at everything". As previously stated, Woods puts his body on the line for every catch, and he yells at himself because he believes he should make every play. In other words, he's a fierce competitor. Barner worked his tail off to be Oregon's leading rusher this year when De'Anthony Thomas was stealing a lot of playing time. None of these guys have any reported off-the-field issues whatsoever.
Personally, I want all 3 of them. How about you?
