Roster depth key to championships, so it's no surprise Seattle has it
The question of which teams have the deepest rosters at this point in the year is an important one and I look at certain criteria to answer the question. In my opinion there are 13 categories that have to get a positive answer for a team to qualify as having solid roster depth. The first is the backup quarterback. A capable backup QB that can go at least 2-2 in a four-game stretch qualifies as a good backup.
