Ask and ye shall receive. With a copy of the preseason game in hand I was able to watch a lot more players (the beauty of rewind) and thus was able to watch some of the more interesting undrafted rookie free agents. In particular, Ladarius Gunter, Alonzo Harris and John Crockett were some common names asked by commentors so below is my impression of them during the first preseason game.
UDRFA: Ladarius Gunter (Grade: B-) – Gunter has been making waves in training camp for multiple interceptions of Aaron Rodgers and added another one against Jimmy Garapolo.
