I'm beginning to notice that the "walk-ons" your GM may sign as you start training camp are also not randomly generated.
For example, in the '08 draft class and following training camp, you may be fortunate enough to acquire - either because he signs with your team or some other team cuts him - a 6'11"

left tackle prospect from Howard who is a better-than-average starter (Bal POT 86 or so). In my latest (yes, another one) Packers franchise he showed up in camp for me off the bat, while in my previous franchise some other team cut him during the season and I was able to pick him up as a free agent.
Anyone else notice examples like this fellow across the UDFA spectrum through your franchises?
