Those of you who follow Dante Pettis on Twitter will have found he has desire to train with one of the NFL’s better wide receivers who is now retired—and we’re not talking about Jerry Rice. Chad Johnson AKA Ochocinco retweeted a request from the San Francisco 49ers wide receiver that Y.A. Tittle Jersey , well, is interesting: Chad Johnson was a very good wide receiver on the field. He also came with character issues that could best be described as “Terrell Owens-light.” I’m sure everyone remembers the “Future HOFer” jacket incident and that’s just the tip of the iceberg. As far as route running however, there were few that could cover Johnson when he was with the Cincinnati Bengals. He even made a list of “Who covered 85, in ‘05.” for the 2005 season. It was almost a circus. It was a domestic violence incident in 2012 that set into motion his departure from the NFL. He turned to the CFL for a brief stint and also found himself for one game in Mexico’s LFA. As far as any sort of mentor or coaching role, it’s limited to a one activity in 2016 when he came to the Cleveland Browns training camp to work with the wide receivers as a guest instructor. There’s a lot that Pettis could learn from Johnson, but there’s always the bigger question: why isn’t he consulting with the GOAT? Jerry Rice has been vocal and open about working with the younger wide receivers, and he also showed up to training camp in 2017 to work with the 49ers.At the same time, there’s a lot Johnson could teach Pettis. Both had similar rookie seasons and I could see a similar playing style develop from Pettis. Maybe Johnson is just the first player Pettis hits up? Maybe he goes like a kung-fu fighter to all the great wide receivers to train, like Terrell Owens, Jerry Rice, Randy Moss, etc. to learn everything he can? The fact he’s trying to train with these guys says a lot about Pettis in any case. Remember when people thought he wouldn’t be focused enough on football? The San Francisco 49ers are in need of an upgrade at receiver. Here’s one option in each of the first four rounds of the 2019 NFL Draft."WhiteFanposts Fanshots Sections 49ers Salary CapLevi’s Stadium Events49ers Transactions49ers Injury News49ers Press Conferences & Conference Calls2019 NFL Draft: 49ers picks, mock drafts, news, rumors, analysisNFL Draft: 1 receiver for the 49ers in each of the first four roundsNew,153commentsThe 49ers are in need of an upgrade at receiver. Here’s one option in each of the first four rounds of the 2019 NFL Draft.PDTShareTweetShareShareNFL Draft: 1 receiver for the 49ers in each of the first four roundsMark Zerof-USA TODAY SportsThe San Francisco 49ers are likely to add a receiver in the upcoming NFL Draft. The team parted ways with veteran Pierre Gar莽on in the offseason, and despite adding free agent Jordan Matthews, Kyle Shanahan’s offense is still in need of additional firepower for quarterback Jimmy Garoppolo. Luckily for the 49ers Frank Gore Jersey , this year’s draft is stacked with quality receivers that are likely to remain on the board into Day 3. Here are some receiving options for general manager John Lynch in each of the first four rounds.Round 1: DK Metcalf, Ole MissNo prospect had a better offseason than Metcalf. The former Ole Miss receiver has cemented himself as a first-round pick after an outrageous combine performance. At 6-foot-3 and 228 pounds, Metcalf possesses the size, power and speed (4.33 40-yard dash) to dominate in the NFL. Kyle Shanahan’s offense would again be blessed with a truly intimidating presence like he had with Julio Jones as offensive coordinator of the Atlanta Falcons in 2016. Metcalf’s ceiling would be sky-high with the 49ers. If San Francisco trades out of the second-overall pick, perhaps with the New York Giants at No. 6 or the Denver Broncos at 10, Metcalf becomes a realistic target.Other options: A.J. Brown, Ole MissRound 2: Hakeem Butler, Iowa StateThe 49ers’ offense excelled moving the ball down the field but routinely struggled in the red zone, inside the 20-yard line. A 6-foot-5, 227-pound receiver with a 36-inch vertical leap can help. Butler, a 2018 second-team All-Big 12 pick, racked up 60 receptions for 1,318 yards and nine touchdowns for the Cyclones last season. He averaged an impressive 22 yards per reception, routinely bullying defenders at the catch point and breaking tackles downfield. Like Metcalf, a receiver of Butler’s caliber would give Shanahan’s offense a much-needed big-play threat and target in the end zone. In most mock drafts, Butler is projected to fall to the 49ers at pick No. 36, but don’t be surprised if his name is called on Day 1.Another option: Deebo Samuel, South CarolinaRound 3: J.J. Arcega-Whiteside, StanfordA strong contingent of the 49ers front office attended Stanford’s Pro Day last week. Lynch Jaquiski Tartt Jersey , Shanahan and new receivers coach Wes Welker were all there to see Arcega-Whiteside’s athleticism in person. He didn’t disappoint, running a reported 4.49 40-yard dash at 6-foot-2 and 223 pounds. The son of two professional athletes, Arcega-Whiteside has made a career of taking advantage of his innate ability. He might be the best receiving prospect in the draft at boxing out defenders and going up for the ball. The Cardinals standout totaled 63 catches for 1,059 yards and an impressive 14 touchdowns in 2018. Arcega-Whiteside is another big-bodied receiver to bolster the 49ers’ efforts in the red zone that should be available in the third round.Another option: Riley Ridley, GeorgiaRound 4: Miles Boykin, Notre DameNoticing a trend? For those that haven’t, every one of the receivers highlighted so far is at least 6-foot-2. Size shouldn't be the deciding factor of which wideout the 49ers should target, but it just so happens that this draft is stacked with big, athletic pass catchers. Boykin is no different. The Notre Dame product entered on to the scene in 2018, catching 59 passes for 872 yards and eight touchdowns. Boykin’s production isn’t eye-popping, but his athleticism is. At 6-foot-4 and 220 pounds, he ran a 4.42 40-yard dash. 43.5 inch vertical and 6.77 3-cone, all very impressive for his size. Boykin’s stock currently sits as at early Day 3, but don’t be surprised if he goes sooner. For a more in-depth look at Boykin, check out Kyle’s breakdown here.Another option: Anthony Johnson, Buffalo
