This clip was Boston College's second offensive possession, leading 7-3. Thomas Castellanos keeps it for a two-yard run to put them at 2nd and eight.
He probably could have gotten a couple of more yards had he not slid, but that's good awareness to avoid taking a huge shot. It's second and eight, and Castellanos throws an OK ball on the slant route but may have led the receiver too much. The ball was catchable, but the receiver heard footsteps and got T-Rex arms, which puts Boston College at 3rd and eight.
Castellanos has plenty of time and throws an incomplete pass(2:53 mark), but Boston College is bailed out by another Missouri penalty to extend the drive. Missouri had two guys spying on Castellanos, preventing him from using his legs.
Boston College gets back-to-back five-yard runs from Treshaun Ward for a first down. Missouri is weary of Castellanos keeping the ball, which provides Ward with some room to run. They give it to Ward again for a three-yard run to make it second and seven (3:27 mark).
The next play may have been a designed run because Castellanos has a tight end open up the seam (3:30 mark, though it's hard to tell how far away the safety was because he's off the screen). It's third and four, and they give it to the running back for no gain and punt from the Missouri 47-yard line on fourth and four.
