Your guide to college football's national signing day

The best of signing days past (0:43)

From Landon Collins' mother disagreeing with his school choice to Isaiah Crowell using a bulldog to announce he was going to Georgia, college football's signing day has provided plenty of memorable moments over the years. (0:43)

College football's early signing period starts Wednesday and runs through Friday.

Recruits are able to sign national letters of intent to the college of their choice, locking them in to that school. Signing the letter of intent prevents other college coaches from communicating with them and shuts down the prospect's recruiting process.

This is the third year of the early signing period, while the other signing day coincides with the first Wednesday in February. Coverage beings Wednesday at 10 a.m. ET on ESPN2 and will switch to ESPNU from noon to 3 p.m.

The early signing period has become more and more crucial to the recruiting process each year, as we have seen the majority of FBS prospects sign in December. In 2017, 71% of FBS prospects and 221 of the ESPN 300 recruits signed early.
