Vogel had decent hang times, and that's pretty much it. His punting average was abysmal (31st, IIRC), but his net punting average was a little below average (22nd, I think) as a result of his decent hang times - lot of forced fair catches. JK Scott and Michael Dickson (who was taken a little before us) were two of the better punter prospects that have come out in some time, so I can sort of understand trying to shore up the position - field position is a pretty important (albeit somewhat hidden) stat. As for the cornerbacks...we'll see. I hope we're lucky in that one of them is ready to play at an at least average level immediately, but our previous CB picks don't inspire confidence.
As always, the most important draft grades come 4 years after that draft is over.
