Guess if diminishing the abilities of a 4* RB that may play a key role in the program's future is your thing...
1. Now that he's with the program, identifying him by the number of stars some recruiting site losers gave him is sad.
2. Insisting that a RB isn't as fast as a team-announced 40-time claims, is not "diminishing" his skills. The team is as likely to lie about a 40 as they are to lie about weight/height.
3. 40 time not a huge deal with RBs...see D. Thomas getting pulled down from behind all year last year for example.
