The best juco I have seen to date was on my brothers game where he got an 89 overall junior juco athlete who he put at wr (which gave him the 89 rating). he had a 95 speed and 90 catch....
The past few days I have seen a dramatic increase to jucos ratings, which include the wr mentioned above, a QB who is an 86, and a tackle who was an 85. All of these are much higher than previous jucos I have gotten. perhaps a patch recently upgraded this?
