These teams very likely believe that the players the took are better QB prospects than Jimmy g.
They didn't draft him or trade up for him 3 years ago. One ok game and a very good half doesn't do a complete overhaul of your view of a player. Especially when he does that wuth the best team in the NFL surrounding him.
You seem to think that being older because you barely played football for 3 years is some type of positive.
I've paid really detailed attention to Brady's young backups over the years - their footwork, delivery mechanics, accuracy and alacrity reading the defense, pocket presence,
command presence, etc.
From Hoyer's first rookie pre-season game appearance, I thought he could have a career as an adequate NFL starter/higher-than-average-quality backup. I thought the same with Cassell.
Mallett started out
way behind Hoyer and Cassell in every area and never improved significantly in any of them.
I saw JG live in practice as a rookie, including against the Eagles in a joint session. Even at that point, he was already miles ahead of both Hoyer and Cassell. For me, his performance in live NFL action at the beginning of 2016 wasn't a "one-off" or anomaly. It was what I expected from him.
I also expect that, if Brady experiences another 2008, JG provides a much better chance of taking a Superbowl-caliber roster to the big dance than any young backup Brady has ever had, a much better chance than Brissett plus any quantity of high draft picks, and a much better chance than about 50% of current NFL starting QBs.
BTW - None of us on this board (or in the media) have any direct, factual evidence of what the Pats may have been "asking" in trade for JG (or if they were asking anything at all) nor what may or may not have been offered. So, we don't really know what his value may or may not be to QB-needy teams around the league or how they view his capabilities.
Sure, all of this is just my humble opinion.
But I'm extremely confident that I'm
not viewing JG through rose-colored glasses. On the contrary, you seem to be viewing JG through some very darkly-tinted windows.
