We're not sure yet, no.
We are sure that he hit a free agency home run with Z, and that Smith and Amos were also very good additions
We are sure that Jaire is a talented player and worthy of a 1st round pick
We are sure that Elgton Jenkins is a talented player who exceeded draft status expectations
We are sure that Darnell Savage at the very least isn't a wasted pick and is capable of playing in the league
So he has hits, as well We all know it takes a few years to really evaluate a class. This year--the year his first draft class is entering their third year, will tell us a lot about that class. Does MVS stay disappointing or take the step forward. Does EQSB emerge as anything more than a big slot backup? Does Oren Burks stay healthy and look competent on the field or does he continue to be a total washout.
We also have some second year players that we should see progress from if he's good, mostly Gary and Sternberger.
If we don't see the progress from a good number of those, then we start to say "wait, a lot of these players aren't working out." It's important to remember that EVERY team/GM has hits and misses; that the evaluation can't be made against perfection, but against his peers, and you look, after 3 years "ok, is his hit rate too low compared to others?" Are the second-year players showing signs that they may add to the hit rate?
Then we'll start to know more. No one thought TT was a good talent evaluator after his first year, either, with Rodgers on the bench, Murphy's career ended after three games due to injury, and Nick Collins being chronically underrated because he dropped INTs. In year two, Greg Jennings was a solid rookie, but not spectaular; Rodgers was still on the bench. Murphy was medically retires. Collins was still dropping INTs and being underrated. In year three, Jennings was good, Collins was good, Rodgers was still on the bench; the rookies weren't contributing much (Harrell, B. Jackson, James Jones). In year 4, Aaron Rodgers was an excellent starter, Nick Collins was a breakout star, Greg Jennings was a #1 WR, and the rookies were Clay Matthews and BJ Raji. By then, we knew.
But it takes time to know. Unless you're lupe. Lupe knows everything pretty quickly, according to lupe.
