The San Francisco 49ers returned to their offseason workouts yesterday, with OTAs set to get going today. The team released some more practice video, and we get to see a bit of special teams work.

This first video features fan favorite Brian Jennings practicing his long-snapping. I think this could make a solid GIF in the sense that watching it over and over again might lull you to sleep. It's important work, but let's face it, it is not quite the most video-friendly of work when there aren't 11 defenders trying to bust through and block the punt or field goal. But practice makes permanent, so fundamentals work is just as important as any other work.

The second video is another short tidbit featuring A.J. Jenkins apparently getting some work in the return game. Over three of his four seasons at Illinois, Jenkins returned 38 kicks for 773 yards. That averages out to 20.34 yards per return.

For comparison's sake, Ted Ginn was third in the NFL last season averaging 27.6 yards per kickoff return. I would imagine the coverage teams in San Francisco are probably a little better than what Illinois had going for them, but even still, I'd imagine Jenkins is among several players getting work simply as a precautionary measure. If he blows up in the role, all the better.
