And today, just hours before the 4pm deadline, he was.
Thomas is second on the Broncos in receptions (36) and receiving yards (402) and tied for the team lead in receiving touchdowns (three) this season.
Thomas, who has spent each of his nine seasons with the Broncos, was dealt to the Houston Texans in exchange for a fourth-round draft pick.
Thomas was the longest-tenured Broncos player after being drafted by the team in 2010. The Texans, 5-3, are now sitting atop the AFC South and were in need of another wide receiver after Will Fuller suffered a torn ACL in a win over the Miami Dolphins on Thursday. The speed that made Thomas' NFL career has diminished, but that doesn't mean he can't be effective as a target for Deshaun Watson.
Fuller, who was averaging 71.9 receiving yards per game and had four touchdowns on the season, had been given a 6.9 overall offensive rating from Pro Football Focus, second best among Houston's offensive players behind Hopkins.
Thomas also is a relatively low-cost gamble for Houston. According to ESPN, the teams will also swap seventh-round picks. The other is money.
With a tough game at the Denver Broncos coming up this Sunday they have been dealt some good news.
For Denver, this is a white flag on a 3-5 season, saves them money and allows rookie Courtland Sutton to see the field more.
