He threw two 'vertical' deep balls to Cameron that were both caught for big gains. The throws to Sims and Stills are plays he usually makes. He just straight up missed those two throws.
I would actually not be upset about this. The problem I see in the NFL with how team's approach QBs is that they don't tailor the offense to the QB's skill set. Case in point, RG3. Now with RT, there's enough tape to know that he just doesn't possess that skill. Instead of forcing the issue they've tailored their offense around WR with RAC skills like Landry and Parker.
