Training camp goes up a notch for the Raiders on Wednesday https://www.raiderslockerroom.com/authentic-antonio-brown-jersey , but the team’s biggest free-agency arrival won’t be there for it.As noted by Michael Gehlken of the , receiver Antonio Brown remains absent as the Raiders welcome the Rams for two days of joint practice. It will be the eighth practice that Brown has missed, due to feet that were frozen by entering a cryotherapy chamber without proper footwear.“It’s good to go against a different scheme,” quarterback Derek Carr said regarding the joint practices, via Gehlken. “I really enjoy it and especially when it’s two really professional teams that aren’t trying to prove their manhood or prove their toughness to each other. Obviously, football is a physical game, but when there are just fights and brawls, I think that’s pointless.”Five years ago, during Carr’s rookie season, the Raiders and Cowboys got into a knock-down-drag-out fight during training camp at Oxnard, California. The following year, the Rams and Cowboys rumbled in Oxnard. Raiders coach Jon Gruden and Rams coach Sean McVay, who worked together in Tampa and who remain good friends, surely will try to avoid any joint-practice ugliness.The Raiders and Rams will meet in a preseason game on Saturday night in Oakland. Brown surely won’t be playing. Although his condition has been downplayed by the Raiders, it’s clear that it’s not minor. At some point, the Raiders need to start worrying about whether he’ll be available for Week One — and if so whether he’ll be effective.

He is a smart and savvy player who runs crisp, clean routes. He has excellent ball skills and reliable hands. He has impressive body control and can make the contested catches and almost never drops the ball.WeaknessesThe UC Davis product lacks some suddenness in his feet, and isn’t the most explosive athlete. He can struggle with maintaining top speed in traffic, and takes some time to work up to his second gear. There were concerns that he wasn’t very fast, but he ran a 4.4 at his Pro Day so he is plenty fast once he gets going. However, he does struggle to separate at the top of his routes, and his success came against lower-level competition.VerdictKeelan Doss has been a tremendously productive receiver for three seasons with the UC Davis Aggies, accumulating over 4,000 receiving yards and 28 TDs. He has all the traits and intangibles that one likes to see in a receiver prospect, and was considered a fifth-round draft prospect going into April. However, a pectoral injury suffered at the Combine not only kept him from doing all the receiver drills, it also likely knocked him out of the Draft entirely. a guy who should have been drafted early on the third day of the draft.Fit with RaidersOakland has addressed their WR position more than any other spot on their team. They have added guys like Antonio Brown, Tyrell Williams, JJ Nelson, Ryan Grant, and Hunter Renfrow. That’s not including some of the guys the Raiders added last year like Marcell Ateman and Saeed Blacknall. But Doss is better than several names on that list and as long as he performs well in camp he should be able to carve out a spot on the Raiders. The guy Doss reminds me of the most is Jordy Nelson, and the Raiders could always use a player like that who is still young.Watch Keelan Doss Highlights here
