I'll speculate. After Tomlin all but said Thomas is too stupid to play, his agent must be pissed.
Can a trade happen?
I think Thomas is short and lacks ball skill too, but let's move on from the obvious and statistical data on his lack of plays in college and as a pro vs the pass.
Its not like we have good safeties right now, so being 3rd string is pretty terrible.
Thomas is #3 on the depth chart behind Will Allen ( Allen will be 34 next season ) a career back up safety, and Golden who's best know for special teams play.
The Steelers traded their 3rd round pick ( mid 3rd round ) to select Thomas. Bad move.
What could we get for him now? He's signed this season and next season.
I'll guess some team would take him for a 6th or 7th.
