Imagine where the Eagles would be if they had pulled off the Mariota trade!? Man he looks so damn good.
As for top qbs, I rank em based on how well they play in the big games. For me those guys are Brady, Rodgers, Big Ben, Brees, Eli, and Flacco. While Eli and Flacco don't put up godly numbers, they still win.
I left Rivers off. Rivers has had an odd career. He can look like the best qb but at the last moment, for whatever reason he doesn't make the game winning play. Sounds weird but that's just how it is. Great qb. Terrible luck. Injuries haven't been friendly to him either.
Luck, Wilson, Newton, Ryan, Palmer are in that next category. Wilson needs to do a lot more growing but he's proved he can win and make the plays needed (even though the d carries him 90% of the time). Matt Ryan needs to show up in big games.
Stafford, Romo, Dalton, and Cutler. These guys will never win a ring. Great flashy numbers and all but that's all. Big games bring out the worst in these guys. Romo is clutch sometimes but he also stinks it up a ton.
The young guys. Pretty much all the guys you mentioned. Derek Carr looks like the next big star qb on come up. He has that fiery personality. Love it. Mariota like I said already, will be a star very soon. Better than Winston. Bortles is coming into his own too. I think I would throw Tyrod in here as well. Amazing athlete, just needs some weapons around him that stay healthy!
The rest are average or trash. Hard to find franchise qbs. Someone needs to take a chance on Rg3.
