I think Jacobs will surprise a lot of people with his receiving skills. He was known as a pass-catching threat in college, but was not used effectively in that role on a consistent basis with the Raiders. But he was 5th in the league in receptions by a running back in 2021 (5 spots ahead of Jones), and 10th in 22 (4 behind Jones). His career target/completion rate is .78, as compared to .75 for Jones. His average YAC stat (yards after catch) was roughly equal to Jones the last 3 years, but significantly better last year. (Source for all those figures - mostly statmuse.com, some nfl.com or ESPN.com).
I don't think we're giving up anything at all in the passing game, and one of the first things LaFleur told him was that he was expecting him to catch a lot of footballs. LaFleur talked about it in his press conference too, saying he's excited to design pass plays for him. At the time we played them last season, I believe he was the NFL's leading receiver out of the backfield, and Lafleur talked a lot about how Green Bay needed to be ready to defend him and take seriously the threat he posed coming out of backfield. So Green Bay knows he offers a lot in the passing game.
Take a little time to watch some of his highlight reels on Youtube - he's pretty to watch. He's a confident receiver, makes it look easy. Very sure hands, always looks the ball all the way into his hands before turning upfield, has excellent body control as he tracks the ball (so that he catches the ball cleanly and solidly), and just all around terrific pass catching technique and discipline. Always seems to already know exactly where he's going the instant the ball is secure, no hesitation or second thoughts - just tucks it in, pivots 90 degrees, and POW he's off. You watch him for a while, you can't help coming away from it feeling like you're seeing a guy with a complete set of well-developed skills as a receiver.
The more I see of this guy, the more excited I am about him. I think this was a wonderful addition. I love Aaron, always will. Will always miss him. But we all know he was going to need to be replaced within the next year or two anyway, and the more I see about Jacobs the more I think we could hardly have found a better replacement.
It's just going to be hard to get used to how many times we're going to see him get caught from behind or angled out of bounds by linebackers. We're not used to seeing that here, but it's going to be the new reality. He's got great burst, but he'll never have Aaron's top gear or breakaway speed. He accelerates to his terminal velocity very quickly, but once he's there, that's as fast as he's going to go. Hopefullly we draft someone with that ability, because they'd pair up perfectly. Linebackers and safeties would have a hard time adjusting.
