I am hoping it was the nerves of being back on Balt, but I just don't know. I am somewhat sure Roman didn't tell him not to go deep...
Rex's Comments:
"I think we did lead the league in vertical passes last year, so we're trying to do that, but you've got to have protection. It starts with protection. And quite honestly, they got after us pretty good in those situations.
"We've been trying to tell Tyrod to believe in your protection, let it hold up and make them pay. We had a big drop, an uncharacteristic drop by Sammy (Watkins) on that one. That's what we're trying to get him to do. We're trying to get him to throw it down the field, hold up protection-wise without him taking off all the time. He did make a couple of good runs and made some good plays. We just weren't consistent.
"I think it starts with protection. A lot of times it starts and ends with protection. We have the ability on the outside. It's tough, though. You have players not in there, Cordy (Glenn)'s out in that situation, but you have to step up. At times protection held up really well, but at times I thought they got outstanding push against us."
Tyrod's comments:
"It was hard. The safeties were playing very deep and they were giving us everything underneath. Basically, we were taking what they were giving us throughout the game."
