Jaren Hall could come back for a 6th year. But realistically, is he going to show more than he has in the last several years already? And will it make up for being another year older? He'd already be the 5th oldest QB drafted in the last 30+ years (Weeden, Weinke, Beck and Mauck being the only older ones)

Puka would be a 5th year
Barrington would be his 6th year (plus two years in Uganda as a missionary)
Freeland is probably the most likely to have solid draft stock this season.

Tooley, Pili, Wilgar aren't likely NFL draft types... But that doesn't likely change with another year. They're also all getting older and it's time to move on with life anyway. LaChance is borderline...but coming back for a 6th year (plus two years as a missionary) isn't likely going to help
