I know second guessing is really easy . . . but I will be for signing vets who have been highly graded by PFF and other teams have let go because they're replacing them with younger guys, if only to "fill in roster" with quality.
Sorry you don't view PFF highly, I do.
You said, "Nobody could have known that when they signed Jackson." - PFF "knew"
Kevin Zeitler - rated highly by PFF every year of his career/a vet G you can count on (6 mil)
Jonah Jackson- not highly rated by PFF in any year (13.7 mil)
Grades this year:
Zeitler - 87.1 (2nd rated G)
JJ - 53.4 (65th rated G)
Well, we actually don't "know" anything when it comes to Jackson. He was signed as a guard, moved to center, then hurt.. then they realized they had drafted a real center who was better at *that* position.
But, you're right, Zietler's been great.
The inclusion of Baun, based on your criteria, doesn't fit. He didn't have a track record of being an impactful player.
The Rams have acquired players in recent years who, like Baun, weren't really successful.. who really turned it up as Rams. Kevin Dotson, A'Shawn Robinson, Austin Corbett, Robert Woods.
And... you've picked the successful cases of this... where are the failed "prove it" deal guys? As someone pointed out... Tredavious White wasn't on a big deal.. he fits that kind of shot.
It's great if you do it and hit... but if you're drafting and developing talent well.. that's good too.
Omar Speights is playing very well as a rookie.. costs a quarter of $$ that Baun costs.. and you control him for four years. Baun? He's a free agent and is set to cash in right away... because he did, in fact, prove it.
