​Kyle Juszczyk impressed by Mike Evans, 49ers rookies ahead of training camp (paywall)“The expectations we had for Mike were already high … he’s a Hall of Famer … and he blew us all away,” Juszczyk said. “He was unguardable in practice, especially in the red zone. And he fits in so well.”As far as the rookies, Stribling and Black, Juszczyk feels both will be able to contribute this season.AdvertisementAdvertisementAdvertisementStribling was given the locker next to Juszczyk’s, and the two have talked about the rookie’s military background (his father was in the Marines) and his fondness for getting his jersey dirty on the field.”Robert Saleh names 49ers’ biggest rookie surprise from last season“Alfred, I know he was a second-round pick and all, but he’s still probably the biggest surprise to me in terms of just how much better he got from training camp, and as the season went on,” Saleh said. “I really think he’s going to be special. His mindset to get better, his work ethic, he’s only going to get better. And when it triggers for him, he’s going to be a bear to stop.”2 undrafted free agents who can make the 49ers roster“Worth III is a superb athlete, too. He’s 6’2”, 226 pounds. He ran a 4.66 40-yard dash, which may not impress. However, he had a 37.5” vertical and an 11-foot-2-inch broad jump. That broad jump would’ve tied Sonny Styles for the longest at the NFL Combine at his position.I’d look at Worth III more as a positionless player who can do multiple jobs. Add in his athleticism, and at the very worst, he could cover kicks for you on special teams and give you a look on scout team in practice. With a little seasoning, he could be a player you use in sub-packages when you’re trying to field a defense full of speed.AdvertisementAdvertisementAdvertisementWorth III played on a horrific defense in college, so his skill set flew under the radar. The 49ers would be wise to put him into different roles, much like in college, and not let an athlete like this walk out the door.”
