As big as today was with the Anquan Boldin trade, I have to say this pair of tweets might have been the coolest of the day.

Several NFL tms approached WSU asst Jim Mastro (who helped develop The Pistol) to learn abt defending the scheme, but he declined — Bruce Feldman (@BFeldmanCBS) March 11, 2013

Mastro told those NFL teams that as long as Colin Kaepernick is in NFL he won't help em with ways to defend The Pistol — Bruce Feldman (@BFeldmanCBS) March 11, 2013

Mastro currently coaches at Washington State, but was an assistant under Chris Ault at Nevada. Ault is credited with creating the Pistol, and there has been a lot of talk about Greg Roman working with him to learn more about the Pistol. Mastro worked with Ault during the development process and likely knows plenty about the offense. I suspect Mike Leach has picked his brain quite a bit since hiring him at WSU.

Plenty of NFL coaches will spend a sizable chunk of this offseason trying to figure out how to defend the various wrinkles of the 49ers offense. Whether it be The Pistol formation, the read option plays, or an assortment of other parts of the scheme, it will be a busy offseason for NFL coaches.
