I've outlined it before but I'm going to go over it again. I really get tired of people saying that Carr was great in 2016 but failing to see that he was just as good last season. It is also very easy to see why he struggled in 2017 and 2018.
In 2017 Carr was fine until he suffered multiple injuries. He had both ankle and back injuries that severely limited his mobility. He couldn't move to avoid rushers and often threw balls off of his back foot as he had a difficult time stepping into his throws. The results were that he was TERRIBLE that season...BECAUSE OF INJURIES!
2018 is just as easy to explain. We had the worst receiving core in the league and two rookie tackles that were turnstiles. Yes he checked the ball down regularly...BECAUSE HE HAD TO! He did not have time to do anything but check the ball down or take a sack. Literally those were his two options.
Last season he was healthy and he got good play from his OL. The result was excellent play until we got into the red zone. I can see some of the blame going his way but I would put much more on Gruden's play calling and our overall lack of receiving options. His top two targets were a TE (Waller) that had never even had 100 yards receiving in a season and a rookie receiver (Renfrow) both of whom were still learning there way in this league.
This year he is playing better than ever. He's got more talent at WR and he has shown that he has total command of this offense. I don't think his receivers dropped a single pass during the first four games of the season. Since then there seem to have been 2-3 big drops every game. I could make an argument that he would be the front runner for league MVP if the receivers hadn't started to get the dropsies. He would easily have a couple of hundred more passing yards and a few more touchdowns.
Think about it. If Agholor makes those catches against KC then we would have ended up winning that game. If we win suddenly Carr would be getting praised by everyone in the league for outplaying and beating Mahomes TWICE! PFF gave him the highest grade of the season for any QB, a 96.0. Take away his last throw and every other throw hit its intended target (23 completions, 4 drops, 2 throwaways and a 50/50 ball in the endzone that Edwards had both hands on and was interfered with). The week before he had the highest grade of any QB that week. Drops by Waller and Ruggs made his numbers look mediocre but his actual play was outstanding.
Bottom line, I am not looking for an upgrade at QB because I don't see one. No one is going to show the command of this offense the way that Carr has this season.
