After going through each position it seems like there are some heavy competition at some positions and not so much at others. The fifth spot at wide receiver and running back are both going to be very competitive and will probably come down to who plays better in preseason. Another competitive group is the offensive line.
The New Orleans Saints did a great drop of getting some very talented undrafted rookies to come in and compete. A few spots will be determined by who plays better on special teams, which is hard to figure out this early, but I tried my best.
