Every year there are also random no name guys that become stars in the NFL. It’s a long shot but you always have to keep an open mind and give everyone a look.NFL.com Analysis:
One-dimensional wideout with speed to burn but a history of injuries that halted any momentum during his career at Ole Miss. Sanders won't be a guy who can uncover on all three levels and his contested-catch finishing is below average. However, he has home-run potential and can draw additional safety help over the top. The injury background comes with a "buyer-beware" sticker, but speed and talent matters. Sanders will get his shot to earn a back-end roster spot as a field-stretching backup.
Every year, there are random no-name guys (CFL guys, arena football guys, supermarket workers, UDFAs, etc) doing well at the beginning of training camp, but fade off, and ultimately don't make the final 53.
There are two big reasons for this:
1) At the beginning of training camp, the coaches tell the established players to take it easy, since they don't want them to get injured.
2) The no-name guys are hustling at 100%, trying to get noticed, trying to make a name for themselves.
As training camp progresses into preseason games, and the level of competition & hitting increases, most of those no-name guys fade off, and don't make the final roster.
