The Titan's season hopes and need for a QB next year will ride squarely on Mariota's shoulders. He is on his 5th coordinator in 5 years (I think) and If he misses any games that will be 5 for 5 as far as missing games in a season. If he gets hurt or plays crappy, I believe the Titan's will be at the bottom of the league. Will they be dead last, I doubt it, but who knows. There will be a lot of good QBs in next years draft IMO. I believe the Clemson kid may go, Frohm (spelling?) may go, Tua will go, Jalen Hurts may go, as well as Jacob Eason, and a couple of others. I'm probably missing a few. I'm thinking next year will be a good QB year.
My issue is I don't think it is a good idea to put a rookie in, in their first year. I know it has worked in some cases, but overall the results are not good, so if the Titan's do go with a QB in round one next year I guess will ride Tannehill as long as we can... I don't know how i feel about that.
