Here's the first Rookie card for the break done in 2008. Jonathan Hefney was an undrafted free agent for Tampa Bay and never ended up playing a game for them. He ended up being on the practice squad for the Philadelphia Eagles and then briefly, the Detroit Lions in 2010. He now plays for the CFL as with most players that were good enough to get a look in the NFL, but not quite good enough to start. Beckett media has 177 cards listed for Hefney. Pretty dang ridiculous for a guy who never saw the playing field. It appears that he was part of most products in 2008 even though he was not drafted.
I sort of like these bronze holofoil cards. Apparently the whole base and rookie print run had these holofoils as a parallel set. They must have been pretty rare as I only pulled 2 of them, both being rookies.
