UPDATE: Although the wording in Rapoport's initial "will visit with" tweet was vague, Jason La Canfora of CBSSports.com reported that Cook was in Buffalo this past weekend. The following was found in La Canfora's article about Cook.
"If you look at the Bill Parcells rules to draft a quarterback I think I measure up pretty well," Cook said after completing a visit with the Buffalo Bills over the weekend and driving to visit his girlfriend in Pittsburgh for a brief respite from his circuit of NFL teams. "He should be a college graduate and start at least 30 games (Cook graduated last year with a degree in media and information) and I started 40. He must have 23 wins; I have well over 23 wins (Cook was 35-5 as a starter). He must have a completion percentage over 60 percent; that's the only thing I don't have (Cook completed 57.6 percent of his passes as a starter)."
Cook was a full-time three-year starter at Michigan State. During his career with the Spartans, 43 total games, Cook completed 57.5 percent of his passes (673-of-1,170) for 9,194 yards, 71 touchdowns, and 22 interceptions. In 2015, Cook passed for 3,131 yards, 24 touchdowns, and seven interceptions.
Cook has good size (6'4") and plenty of experience in a pro-style offense. He also has good arm strength.
The quarterback's biggest concern is his accuracy. He's never completed more than 58.7 percent of his passes in a season.
Cook is viewed by most draft analysts as a day two pick in the 2016 NFL draft.
