I don't know what your reasons are for entering the NFL draft so I will provide a few reasons that it would be good for you to stay in school.
1. Academically: If you come back for your senior year of football at Georgia Tech, you will be able to graduate and finish your degree. This is a big pro for coming back to school because it allows you to be better prepared for the future. You wouldn't have to return to college to finish your degree like you would if your leave early for the NFL.
2. Financially: This is another great reason to come back for your senior season. You may think this seems wrong, but where you get drafted determines the value of the contract you will get if you are drafted. After looking up draft projections, I've seen you going anywhere from undrafted all the way to the 3rd round. It will be very difficult to get drafted as a 4th or 3rd rounder unless you refine your skills as a wide receiver quickly before the upcoming NFL draft. You have been blessed with great size and athleticism, but that is not the most important part of being a WR as you probably know.
But let's say you come back for your senior year. If you put in a lot of work this offseason and next year by working very hard on your catching, route running, and other aspects of a being a wide receiver, then you will see an improvement in your production. All of this combined with a successful season next year will raise your draft stock higher. You may lose a year of earning a salary in the NFL, but the rewards of becoming a higher draft pick will be worth it. You will be a better WR than you are right now and you will earn a better contract, more high paying contract as a higher draft pick.
I'm not sure of your reasons for declaring for the NFL draft, but whatever happens, we support you and hope your career turns out great!
