In their actual NFL uniforms it is normally the Donruss release. Of course, those photo are normally from the rookie camps or the start of training camp itself, but they are usually in their NFL uniforms. There are 2 other large NFL releases, Score and Panini prestige, but almost always the rookies are in college uniforms with mention of their NFL team they were drafted by.
Smaller, more niche releases, especially those released later in the season, will have them in NFL uniforms. I don't go after those sets so others can chime in.
Tired and trembling
I am descending,
will I have to stay here
and live this life again?
