Yup, Becton would be a fit but he probably won't be there at #30 unless the pundits are just dead wrong about him. Not saying it can't happen. Last year most pundits and even posters here said Irv Smith would never make it out of Rd 1 because certainly the Patriots would take him if nothing else. He lasted until the back half of Rd 2. That said, Smith was more of a question mark at the time. Becton seems a lot more solidly in the top half of Rd 1.
Agree also that Peart would be a decent get at #62. It's probably too high but if he's your guy, grab him because he probably won't be there at #94. There's a group of tackles that kind of show up in the back half of Rd 2 for some mocks that includes Niang, Wahogoh, and Peart. I would think one of them is there and all 3 sorta fit. All will need some development time, but Wagner can hold the fort for a season if needed.
Austin Jackson is a guy I wonder about as well. Opinions on him seem mixed. Some really like him based on athleticism and potential, others say he needs a lot of technique work and don't like him as much. Shows up in the back half of Rd 1 a lot, but also have seen him later. Might be a guy who slides. Not sure if he makes it to #62, but he's a guy I'm watching in a couple of weeks. He'd certainly be a scheme fit for the Packers.
