I agree with your assessment of our WR corp being just as much of an issue as Rees. We definitely need a more mobile QB who has the arm strength to test a defense vertically. That being said we also need receivers who can test a defense vertically. TJ Jones is a good WR, but not explosive. Riddick is explosive in tight spots, but I dont see the true top end speed from him. He is more quick and shifty than fast.
I do believe though that Davaris Daniels is going to be the best true ATHLETE we have seen play WR in some time. Kid is fast, explosive and can jump through the roof. He needs to hopefully gain a full understanding of the offense and put on another 10 lbs before next season.
GAIII if moved back to WR can definitely provide some explosiveness. Also, do not sleep on the guys who appear to be coming in with next years freshman class as it stands right now. Ferguson is vastly underrated as an athlete and is built like a college junior right now. Greenberry might not have top end speed but is 6'3, long and attacks the ball incredibly well. Chris Brown would be the fastest WR on our roster right now. The cavalry is definitely on the way. Hopefully the upperclassmen can hold down the fort until they arrive. If Golson develops physically and continues his natural progression as a QB he will challenge Rees as the starter next year. Having a QB who is actually a threat to keep it on the read option, tuck it an run if everybody is covered, or even run a little speed option or be a threat on roll outs will help alleviate the lack of a playmaking WR until somebody steps up and takes that role next year.
I dont think Brian Kelly will have trouble generating a high scoring, fast paced offense, but right now I think he is playing the hand he's been dealt.
We just went on the road, played our wost game of the year, and came out with a W. Hard to argue that we were outcoached. If that were the case, we would be 1-3, not 2-2.
I relate this to a Roy Halladay or CC Sabathia. As a pitcher you're not going to have your A game every time out, but the good ones go out there and find a way to win even when they don't.
