U already know. Miami has a league high 44 players on the opening day, active rosters (practice squad not included). However, 15 of those players never played in the ACC having been Hurricanes when they were in the Big East.
The next highest amount for an ACC team was 28 and it was a surprising team to me.
While Miami has not seen a dropoff in NFL talent during lesser seasons, FSU has placing just 25 players on active rosters. The Seminoles had 46 in 2006.
The total of 249 players is a six year low for the ACC.
