Not “so much”. Slightly.
At this point he just seems like the more polished player, as his quickness and agility, especially getting off the line are better. Also like how slippery he seems.
Dobson seems more in the Braylon Edwards mold, and once he learns to use his size and length better he’ll rapidly improve. He also needs to attack the ball better, seems like he’s not used to how close DBs will be on him in the NFL.
Still think both players will be good, but at this point Thompkins seems like the better of the two, three weeks into their rookie seasons, which is admittedly way too early to judge anything.
