Kid is a monster. As an NFL prospect, he may have more to offer than EB. You're talking a franchise DT for 12 years. That truly is hard to come by.
Titans need a viable option at QB. I don't know if there are for-sure options that will be worth a high first round pick.
Probably what will happen is Bud Adams will trade down to allow other high-profile (wealthier) teams to capitalize on the no-cap that's probably coming next year, plus Adams is resistant to spending money. Maybe take Pike with the 15-20th pick and then have additional picks in pretty much every round.
