I think Starocci would be crazy not to wrestle if he is healthy enough to go.
Winning NCAAs is probably his only realistic way to qualify for Olympic trials.
Winning a 4th would cement his legacy in the sport. Otherwise, he would likely be forever stuck behind Brooks and only in the conversation with three-timers like Nolf, Nickal, and Retherford.
Winning a 4th would likely provide him with some endorsement money and further opportunities.
Not wrestling would likely end his ties with NLWC, the best place to train.
Not wrestling would likely alienate him from the coaches and many guys on the team with whom he is connected for the past 5 years.
And, last but least, not wrestling would make him the subject of conversation for who-knows-how-long on wrestling forums. For a while, references might surpass Downey, Ferrari, Spencer Lee, and of course Jimmy Cinnabon
