Why not? Ryan Lindley proved to be nothing special. I understand that was against the Seahawks, but that’s the type of team the Cardinals will have to face in the playoffs, that is unless they draw the Panthers or Falcons. That would be a much more manageable game for an undrafted rookie free agent.
Thomas performed well in his tenure at Virginia Tech. In four season with experience and three as the starter, Thomas accumulated 9005 passing yards. He completed 228/403 passes, a 55.6 completion percentage. He threw 53 touchdowns and 39 interceptions. Standing at 6’6″ and 254 pounds, the numbers are there. In his relief for Drew Stanton in week 5 against the Broncos, Thomas completed only one pass out of eight attempts, but the completion was an 81-yard touchdown to Larry Fitzgerald.
So the numbers are there, and the intangibles are there. Thomas just needs a little coaching, but isn’t that why the Cardinals hired Bruce Arians in the first place? They’ve won 11 games this year with virtually no offense, so all they need is a spark. If Thomas beats the 49ers next week, the Cardinals will likely face the NFC South “champion”. If not, they’ll likely travel to Dallas. This isn’t to say Thomas will be starting in the playoffs, but it isn’t impossible.
