I don't necessarily disagree, but some of the issues with Zaire as the bowl game wore on was that tied to him not being the beneficiary of first team reps over the long term the way EG was. I imagine that Zaire's weakness in finding secondary receivers is a function of experience, not anything else. So that would improve over the offseason and into the fall.
Remember that, for the first two-thirds of the season, Kelly, when asked about whether he'd replace a fumbling, INT-prone EG, said, essentially (or actually, as I think about it, said literally), "No, we stay with Golson. We don't have anyone else." Those were his very words. That tells me Zaire wasn't viewed as ready and wasn't getting the reps he'd need to really improve and take over. Or else Kelly was sandbagging, which I doubt.
My point being that Zaire could definitely be what we need, given the reps and prep that EG got. But I still want them both. Golson is a lot better than he looked the second half of the year; he looked confidence-shaken -- underthrown passes, trying to do too much -- and yet the ball security issue is a huge red flag. He didn't get better at that, even when he knew it was a proclivity.
