Some in the know say Cam Ward is #1 with Mario. I think it's a good move bringing in Howard. You already know what Howard's camp is looking for. If the number is too big with Ward or he wants to delay his decision, Mario can counter with, "We need an answer in 24 hours or we have to move on. I promised other candidates a decision."
By bringing in both guys on consecutive days, it takes away some of the player's leverage because you can tell each guy that the other guy is a better value and/or ready to commit.
I also hear rumors that Dante Moore will get an on-campus visit as well. I think Moore is only a take if he's willing to sit. Indications from his dad is he wants to be developed, so that may mean a willingness to sit and learn for a year. Bringing in Moore could also could cause a ripple affect with Emory and the 2024 QBs. It's a tough decision Mario has to make.
