Here is the truth. No one heres knows crap about Mac Jones outside of the fact he isn't a complete bust. He had a solid rookie year, but i've seen plenty of QBs have a solid rookie year and then totally fall off the rails. I've also seen plenty of QBs have a solid rookie year and then make big year 2 leaps. No one knows for sure what will happen with Mac at this point. Any reports in Spring or Summer will likely be positive, as they are for any player. We will have SOME idea once preseason hits, but not really until the regular season starts and the bullets start flying.
I'm hopeful on Mac, he was my 2nd favorite QB coming out last year, I was high on him then and I will stay high on him now. But I will say what I have said time and time again, and my opinion WILL NEVER CHANGE. You either have a great QB, or you try to upgrade that position. A top 16 QB does little for you. A top 10 QB does little for you. Top 5? Now we're talking. I have absolutely no interest in making the playoffs most years in a now over inflated 14 team format only to be bounced before the final 4 year after year in the hopes that somehow someway the sky parts in a rare example of a team without an elite QB or an elite D winning the championship, which is the exception and not the rule. Particularly when you pay a good ti middling QB the big bucks.
Until Mac proves he is a great QB I say hold him on his rookie deal and try hard as we can to break through while we have the advantage of a massively underpaid QB, which looking at the rest of the 52, we are not taking advantage of. If come year 5 he shows he isn't that level of guy, trade him for as many first round picks as we can and try again. Anything else is settling for mediocrity or playing against long odds.
