For me, biggest question is how many TEs they want to have on the roster. If they want 4, they have to eliminate the FB or go with 5 WR. Or maybe Ham becomes a HB? All depends upon the needs of the scheme.
Second biggest question is pass rushers. We potentially have J. Holmes and Robison as interior pass rush specialists. Do we really need two, with two quality 3T players ahead of them in Richardson and Jaleel Johnson?
