I think it depends on what other talent we acquire. For example, if we sign Jennings and draft Hunter, then Hartline is probably #3 at best, if Matthews doesn't make progress. I we sign Wallace and draft Allen/Woods/Wheaton then Hartline is still probably fighting Matthews for #3. If we go on the cheap and just add through the draft then he has more value as a mentor. Frankly I think WR is one spot we could immediately FIX this offseason, which would put our offense in "almost done" mode.
I don't think Rishard Matthews, the phantom menace, will be on the team next year. He can barely get on the field with this pathetic offense.
