College football’s 2021 National Signing Day is officially in the books. Alabama signed the best class in modern recruiting history, with Ohio State, Georgia, Clemson, Oregon, LSU, USC and Texas A&M rounding out the next tier of top hauls for '21. Every FBS program inked recruits to a National Letter of Intent on Wednesday or in the early period in December, which means coaching staffs should have a good snapshot of how their program looks for the upcoming season. And if teams didn't fill their needs on the recruiting trail, a trip to the transfer portal could be in order.
