We have studied the mocks. We know the team needs. Now it's time to offer up our best educated guesses on which players the Redskins will target in thefourth round with the102nd and109thoverall picks.Obviously if a talent at a non-need position is on the board, the Redskins may have no choice but to deviate from their plan, which is fine for the fourth.For each position, I listed prospects who fit into the range of the Redskins pick and a player who could slide down. Here is a look at the third-round options.Offensive line...Brandon Mosley, OT, Auburn...The former tight end is a raw prospect, but scouts love his mobility and athleticism...Ben Jones, C, Georgia...the best of the non-Peter Konzsnappers, Jones is an enthusiastic tough guy. Redskins need backup center and worst case could slide Will Montgomery to guard if Kory Lichtensteiger's recovery from knee surgery is slower than hoped...Tony Bergstrom, GT, Utah...thecrazy strong (32 reps at 225 lbs)and versatile lineman started 39 games for the Utes primarily at right tackle. Will play as a 26-year-old rookie, but nobody will complain aboutBergstrom's age if he's tossed into the fire quickly...Backup plan...RG3's college center Philip Blake (Baylor) is another likely fourth-rounder and this one can play either position inside.Secondary: De'quan Menzie, CB, Alabama...pretty sure nobody will object to adding a member of the Crimson Tide's secondary. Menzie started 20 games the past two seasons, playing outside and in the slot. Pedestrian speed (4.74) pushes him down in the draft...Brandon Hardin, FS, Oregon State...stud athlete with size (6-foot-3) and speed (4.44) who also played corner for the Beavers. Pro Football Weekly report on Hardin says he "has desirable intangibles and at worst should be a versatile, valuable backup and core special-teams player."...The Redskins have nearly revamped the entire secondary - and plenty of more work needs to be done so any rookie has a great chance to stick and contribute.Backup plan...Could Jayron Hosley's reported failed drug test at the combine drop the Virginia Tech corner down into the fourth? Eh, guessing not, but South Carolina strong safety Antonio Allen should be in that range. The second-team SEC performer led the Gamecocks with 88 tackles last seasonInside linebacker: James-Michael Johnson, Nevada...Not ready for prime time play, but Johnson is a physical threat who could be special dynamo while he learns the position behind London Fletcher...Really not seeing a backup plan here. As mentioned in the third-round blog post, position depth is very limited so if the Redskins want an ILB, better jump on when they can.Running back: Bernard Pierce, Temple...Cited the touchdown scoring Pierce (27 scores last season) as a potential third-round sleeper (at least for me anyway), but his real projection is early in the fourth. Could be the Mr. Inside to Roy Helu's Mr. Outside...Backup plan...Robert Turbin, Utah State...Todd McShay has the 5-foot-10, 228-pounder with 4.48 speed going ahead of Pierce, while Rob Rang the opposite. Turbin reportedly visited Redskins Park during the draft evaluation process.Tight end: Ladarius Green, Louisiana-Lafayette...McShay projected Missouri's Michael Egnew to the Redskins in the fourth. We will call that the backup plan. Won't argue with the guy who actually studies the game tape, but after studying up on Green, I am intrigued by the near 6-foot-6 target with 4.47 speed who averaged 18 yards a grab as a junior. I know, I know, nobody wants to see Chris Cooley go. Considerthe potential picking of Green planning for a rainy day...And the winner is...Seeing as I projected offensive tackle Zerbie Sanders (Florida State) in the third, I'll say the Redskins go withBergstrom at 102 and Hardin at 109. Yes, I'll resist the temptation to the rule the world and say Pierce gets the call. Unless Tim Hightower re-signs (until he does, I'm ignoring the nice talk between player and coach), there is a definite need for another back, but maybe a veteran is best...Bergstrom'sability to potentially help at right tackle and inside isa nice selling point...At safety, come on, just look at the depth chart. They can do better...Looking at the board, going with an ILB in the third might be the way to go. Still decent offensive line options (especially inside) available, but there are minimalinside linebacker choices. Get on the record people. Whodo you have the Redskins taking in the fourth???
