The senior bowl is a showcase event that features the top senior and redshirt junior NFL draft prospects in college football. The North and South teams are coached by NFL coaching staffs, and the game is televised nationally on NFL Network.
Each team typically has a maximum of three quarterbacks. With the latest additions of Dak, USC's Kody Kessler, and Stanford's Kevin Hogan, that leaves just one more spot at QB. The other quarterbacks who had already accepted invitations include Carson Wentz from North Dakota State, Jeff Driskel from LA Tech, and Jacoby Brissett from MSU's next opponent, North Carolina State.
A strong showing in the bowl game combined with a good week of practice and solid performance in the Senior Bowl would be huge for Dak's draft stock. Right now he's being projected in the second to third round, but that's not a guarantee. Impressing the scouts and NFL coaches in person wouldn't vault him to the first round, but it could solidify a selection in the second or third.
Practices for the senior bowl will begin in one month, and those can also be viewed on national television via NFL Network.
