Apparently, I was way off the mark. He is entering his 5th season and has yet to take over and keep the starting role. Some of his career has been plagued with injuries. For example, he did not play in 2008.
I was fortunate to see him play while I was in Utah. His last year at Utah is something to be amazed by with 2900 yards, 32 TD and only 4 INTs. He obviously was a great QB at the D1 level, but continues to experience some obstacles achieving success at the NFL level. He is currently the backup QB to Shaun Hill.
