Niners would be lucky to get later in the draft"The San Francisco 49ers need help at edge rusher Ahkello Witherspoon Color Rush Jersey , safety, cornerback, and wide receiver. They could also stand to build some depth at a couple other positions. Since it’s all but a guarantee the team goes defensive line in the first round, I’ll give you one sleeper at the other three positions mentioned. Let’s start with safety.S Juan Thornhill, VirginiaThornhill is a name that the diehard draft fans will know, but is a relative unknown to the casual fan. Thornhill is a name that gets lost when you talk about the top safeties in the draft. After his ridiculous combine, he started to become more and more popular. The 49ers need to get more athletic on defense. That way they can do a better job of making plays in space, which leads to better tackling. Thornhill ran a 4.42 40-yard dash. That speed shows up when he’s asked to track the ball down—whether going forwards or backwards—and make a play. Thornhill is aggressive against the run. He had the most tackles of any draft eligible safety. Sometimes he can get a little too aggressive and miss, but he also gets to a lot more plays than most. Thornhill is really good as a deep safety, but has the athleticism to drop down in the box and make plays. If available in the third round, the 49ers would love to get their hands onHonorable mention: Utah’s Marquise BlairWR Anthony Ratliff-Williams, UNCIf there’s a Kyle Shanahan type receiver out there later on https://www.49ersfanshop.com/C.-J.-Beathard-Jersey , it’s this guy. Ratliff-Williams ran a 4.46 40-yard dash and jumped 35” in the vertical. Unfortunately, there aren’t any shuttle times on the 6’1, 205 pound receiver. Ratliff-Williams has the other intangibles that the Niners seem to covet. He’s clearly athletic. Ratliff-Williams was the kick returner at North Carolina, where he had two returns for touchdown in his career. He also was a punt gunner, not to mention a great blocker.We care about Ratliff-Williams the receiver, though. He is used to timing routes underneath, and big shot plays down the field. Ratliff-Williams isn’t the most nuanced receiver when it comes to route running, but he gets open with speed.Check this route out below at 7:22.You see the speed, and Ratliff-Williams ability to adjust. One area that the former QB also excels at his jump balls. He’s been known to “Moss” a defender or two.He’ll be available on Day 3 of the draft, and the 49ers would be smart to give a talent like Ratliff-Williams a shot.CB Jamel Dean, AuburnTo me, he’s the best corner in the draft. That probably feels like a hot take. I was on this train before the 6’1 Matt Breida Jersey , 206 pound cornerback ran a 4.3 flat. Everything he did at the combine was impressive. I found out about Dean watching Georgia’s Riley Ridley. Dean erased him. But he did that to the majority or receivers he faced in the SEC this year.There are plenty of high end athletes that play corner. There are very few high end athletes that are also technically sound. You’ll see plenty of defensive backs fall for the first move the receiver makes and panic. Dean is always under control. He trusts his athleticism. The play above where he breaks up a pass really tells the story of the player. Fast, physical, and a finisher. I know the team brought in talent to compete, but Dean has the ability to be special.Who is a sleeper that you want the team to draft later in the draft? The San Francisco 49ers entered Week 15 with a serious shot at the No. 1 pick in the 2019 NFL Draft if they lost their last three games of the season. They beat the Seattle Seahawks on Sunday, derailing that effort, but snapping a ten-game losing streak to the Seahawks.There have been plenty of moments this year where the 49ers have played well only to come up short. The “elegant tank” has been a regular part of the discussion around these parts for the last two seasons, and whenever something a little fishy happens, the first thought is that it’s a convenient part of getting that high pick.We saw another example on Sunday against Seattle. At the 10:41 mark of the fourth quarter, the 49ers and Seahawks were tied 20-20. Seattle had tied the game the previous drive with a 10-play, 75-yard drive that saw Chris Carson rumble for 53 of the yards. The Seahawks run game, stifled for the first three quarters, was showing signs of life.The 49ers took over at their own 25 with 13:51 remaining in the fourth quarter and drove into Seattle territory thanks in large part to a 30-yard Dante Pettis reception. At 10:41 Trent Taylor Color Rush Jersey , they faced a 3rd and 7 at the Seahawks 28 yard line. They were well within Robbie Gould’s field goal range, and saw it would have made sense to take a shot to try and convert another first down.Instead, Nick Mullens handed the ball off to Matt Breida and he was swallowed by up Frank Clark after a one-yard gain. The 49ers settled for a field goal. Here’s a look at the play with the handoff slowed down.My Twitter feed was instantly filled with people talking about it being a tank-worthy type of play. They play for the three points and potentially set the Seahawks up for another Russell Wilson fourth quarter comeback.The 49ers would actually get stout play from their defense each of the remaining Seahawks series, but if you re-watch the play, there is something notable that the announcers picked up on. If Mike McGlinchey successfully blocked Clark on that play, Breida would have had a sizable hole to get to the first down marker. He might have needed a block from Dante Pettis in front of him, but there was a lot of grass between Breida and the yellow first down line.We’ll likely never know for sure what Shanahan’s thought process was on that play, but it made a lot of sense. Clark was bringing the heat and the play design used that aggression to try and take him out of the play. George Kittle had motioned over to Clark’s side, and at the snap cut to the left to fake a block that appeared to set up an inside run. The safety over top cut in when Kittle moved and that opened up the space past the line of scrimmage.The play didn’t work out this time, but the design was sound.
