First of all, great post. You made a lot of valid points and concerns.
For starters, if we go into next season with this crew and Wallace gets hurt then we are screwed indeed lol. That also applies with almost every team and their #1 WR. Heck even A.Rodgers had a tough time without his #1.
i also agree on Davis and Williams part. If they fall out of the top 10 then we should seriously consider them. They have AJ Green written all over them. I disagree tho when it comes to Ross. I don't see what he brings to the table that we don't already have. (Fast, deep threat, unpolished routes, and injury prone) sounds like a Perriman to me but without the 6'2 frame. I just feel like we don't have enough footballs going deep to feed all our deep threats.
well I guess il move on to Perriman. He had a great rookie season when you consider that he never really practiced with the team. He had a few focus drops early that were over exaggerated. I say that because he had twice as many huge plays that only a handful of WRs in the NFL can even attempt to make. He finished the season strong as he settled in and got more opportunities. I think he's poised to have a thousand yard season if he starts and has a full training camp with Flacco. (I can't defend his knee because I also hold my breath every time he goes down)
to conclude, I would t say taking a WR is a must in the first round because we have a stud in Wallace and a stud in the making in Perriman. I would say that we need another solid WR that brings a different skill set to the table to open up the deep passing game. Someone like Ju Ju (USC) makes a lot of sense to me.
