Seeing several comparisons of Tua's situation to that of Fields in CHI. Bound to happen. My take:
Tua had an average situation so far from my limited understanding of MIA and the local media's take on things. Coaching & surrounding talent didn't really HELP Tua much, but he's also had his injuries and hasn't produced many WOW or explosive plays that lead people to buy in hard. He's still a "wait and see" QB...much like Trubs in his first several years, probably with more upside than Trubs.
In CHI on the other hand, Nagy was clearly pissing in the gas tank of the offense AND the OL / WR talent were not even average as units.
Fields still has a pretty nice deep ball, can run like a mofo, and pops out at least a few WOW plays each game, even with Nagy's O not allowing & even actively sabotaging any consistent success, threat of a run game, and reliable OL protection. We all saw what similar holes did to Cutler, hell even Rexy...dudes began seeing ghosts with happy feet, reduced mechanics, and forced throws. Fields looked better with worse than Tua IMHO, but it's just me. I'd believe the stats show he's better so far as well. As fans we're simply very snake-bitten and hesitant to buy into anything, which is 100% understandable. So we wait n' see, and prepare for plan B. So'kay.
I wish Tua & Fields both well, but would put my money on Fields to have a better career when all's said and done. Still early for Fields. No excuses now for Tua, unless his HC & OC are total numbnuts like Nagy, which hardly seems possible to that extent. ?
