I think they should draft Harrison Jr., and play the next few seasons with no QB, just like they have been doing the last couple of years, that’s worked out great for them.
What all of this really boils down to is that there are some people here who simply have a boner for Marvin Harrison Jr., and because they can’t come up with any legitimate reasons to pass on any of the 3 QB’s they start to play the “ he’s not guaranteed to succeed” game. Which, if true, means you should just trade every pick for veteran players, because no rookie is ever guaranteed to succeed.
