well i believe that 1999 rams championship team had warner, fletcher, farr, and jenkins – all undrafted and all major contributors to that team. i’m sure there were more than that.
rams need to hit on a couple in order to get an edge on the other teams.
I don’t count Warner as a UDFA because he was already Green Bay’s UDFA in 94. I see him more as a low-market FA. That includes also Gruttadauria, Nutten, and McCollum.
But your point of course is a good one.
Calculated my way, with the Warner caveat,, it’s actually Jenkins, Fletcher, Farr, and Horne.
