And yet the guy who personally played a role in drafting Thomas decided Lindley not Thomas should play. And then after 2 bad performances he names Thomas the starter and 2 practices later, he decides to start Lindley. People are missing the point, even Bruce Arians who has every reason to believe in Thomas, doesn't right now.
I go back to the pre draft rumor on Thomas, when he was at Va Tech he contacted QB Guru Steve Clarkson(ex San Jose State QB) and wanted to pay Clarkson to work with him in the offseason. The rumor is Clarkson brought him in for a workout, and then after the workout told him it would be unfair of me to take your money, you are NOT a QB, you should move back to TE. So Thomas hired a different QB coach, slid down draft boards and appeared to reinforce everything Clarkson saw,
He has great size, he has a strong arm, that doesn't mean he's a QB and at least so far even Arians isn't sure. The thing is the NFL during the season it's tough on a 3rd string QB, you don't get many reps, even with Arians and Moore talking to him, he's not getting actual work, so his progress in the preseason has been stunted.
