I doubt any team is going to be willing to give up a 2nd for him so a third or fourth is only as much I can see The Ravens getting. A third would be good for The Ravens but a high fourth round wouldn't be bad either. I can't pretend like The Ravens haven't had any success with lower round picks from Jarret Johnson,Dennis Pitta,Jason Brown,Leron McClain,Ovie Mughelli,Ed Hartwell, ,Edwin Mulatio, and Kyle Hugecheck (lol) whom all have been fourth round picks. Even right now The Ravens have fourth rounders such as Tavon Young , Alex Lewis, Chris Moore, Matt Judon, Kenneth Dixon. Brent Urban, Lorenzo Taliferro ,Zadarius Smith, and Buck Allen who we all saw become solid contributors for the team last year or are expected to be contributors for the team at some capacity.
If Timmy Jernigan was traded today for a high fourth round pick then I can't say it doesn't benefit The Ravens given their success with finding starters that were fourth round picks in past. Who to say they won't be able to find a starting right tackle or guard with the fourth pick they get from trading Jernigan or maybe even defensive tackle/end.
