Great effort. Thanks for posting. I hate to sound critical but you twice wrote that EDGE is our biggest need and then you named our players that go 5 deep.
If Floyd and Ebukan are our starters and you like OBO and Polite where is the desperate need? The position of greatest need right now is PK because we don't have one. I also have to say that QB depth looks like a big need to me. If Goff goes down who plays QB? The kid who was our 3rd stringer looked good in PS but has never taken an NFL game regular snap and Bortles is still a FA. So, the most important position we have a starter and an inexperienced backup. If Noteboom isn't healthy and Whitfield goes down who plays LT? That spot looks thin.
At RB, we have Hendu, Brown and Kelly. Hendu played sparingly and had some success. Brown played very little and got hurt. Kelly almost never saw the field and doesn't seem like a big time talent. So RB is a definite need.
I have no problem with your mock itself but disagree on your reasoning on to which are our most important needs. Great job and thanks again for sharing.
