One of them is a method of rotating the teams every other round so that it ensures every team gets the first pick in a round. The other is designating which position each team can draft per round.

The eight teams had to select a quarterback in the first round, and the Michigan Panthers selected Shea Patterson, who played for the University of Michigan Wolverines for his college career. Here are the quarterbacks drafted by each USFL team Tuesday night in Birmingham, Alabama.

Michigan Panthers — Shea Patterson, MichiganTampa Bay Bandits — Jordan Ta’amu, Ole MissPhiladelphia Stars — Bryan Scott, Occidental CollegeNew Jersey Generals — Ben Holmes, Tarleton StateHouston Gamblers — Clayton Thorson, NorthwesternBirmingham Stallions — Alex McGough, Florida InternationalPittsburgh Maulers — Kyle Lauletta, RichmondNew Orleans Breakers — Kyle Sloter, Southern Miss

The snake draft means that the team selected last in the first round would draft first in the second round, and the draft would go in reverse order if the first round, meaning the Panthers select last in the second round. The team picking second in the first round would eventually get a first pick in a round, as would other teams during the event.

A position is designated for each round. For example, teams can only select defensive ends or edge rushers in rounds two, three, and four. Offensive tackles, cornerbacks, and quarterbacks will complete the first day of drafting, which began at 7 p.m. ET and is scheduled to end around 10 p.m.

Day two of the draft is scheduled to begin at 10 a.m. on Wednesday and will continue until all 35 rounds are complete.
