49 Of 144 Early Entries Went Undrafted

So why wouldn’t college football let players test the waters and then return to college football if they aren’t drafted, or if they don’t like where or how low they went? First, that approach would cause more players with remaining eligibility to roll the dice and possibly leave, thinning the ranks of college football. Second, it would make NFL teams potentially squander draft picks on guys who then say “no thanks” to playing under a low-round contract for a low-rent team, and return to school in the hopes of landing in a higher slot and/or with a better team a year later.

Don't like it at all for the guys who go undrafted.

Would a college turn down a person who got a BS from them cause they tried to test the job field only to find out the market isn't strong and now they want a MS?
Don't get punishing young people for trying to make money. The NCAA makes millions off these kids and forces them to make tough decisions in an undecided market for them.
Some are well off like Rosen, others are like Dez Bryant who was born in a terrible situation and well frankly never got the proper education due to his upbringing. More are like Bryant coming from a tough background than Rosen. And, some of those men don't have elite athletic abilty that Bryant did and they aren't 100% certain they will get picked in the draft.

The NBA and NHL face the same dilemma. And for the NBA, the draft is only 2 rounds.
