And Thomas got right to work:
He finished with three catches for 61 yards as his new team beat his old team, 19-17, thanks in part to questionable coaching decisions by Vance Joseph that cost the team three points just before half and ultimately cost them the game when the Broncos settled for a 51-yard field goal as time expired. Kicker Brad McManus missed wide right and Denver lost for the sixth time in seven games and fell to 3-6 on the season.
So how did the Broncos look from the other side of the field?
"That's what they do over there," Thomas told NFL.com's Mike Silver. "I ain't a part of that no more. We like to win over here."
But Thomas still has fond memories of Denver, where he spent the first 8.5 seasons -- and big fans. After the game, Peyton Manning's kids waited for the wide receiver outside the locker room. and Manning's son was already wearing Thomas' new Texans' jersey.
