The Arkansas coach took out his frustration in numerous ways during the first half — primarily on his headset (thrown to the ground), paper cup (also thrown in disgust) and Razorbacks quarterback Tyler Wilson.
And that was with No. 14 Arkansas up 24-0 in an eventual 38-28 win over Troy.
The lackluster performance — particularly in the second half — was hardly what Petrino and the Razorbacks (3-0) were looking for after opening the season with two convincing wins in which they outscored their opponents by a combined 103-10.
It also was anything but a building block as Arkansas prepares to open Southeastern Conference play at No. 2 Alabama this week.
