CLEVELAND (AP) — Mitch Trubisky promised he’d be more aggressive and was, testing Cleveland’s secondary with some long throws and moving Pittsburgh’s offense effectively in the first half. Now he’s got to put a complete game together. Trubisky showed some signs of breaking out of an early season funk before bogging down after halftime as the Steelers lost 29-17 to the Cleveland Browns on Thursday night. For 30 minutes, Trubisky looked good. He moved well in the pocket, stretched the field with some deep balls and had the Steelers (1-2) leading by a point at half and looking to hand the Browns (2-1) their second loss in four days However, Pittsburgh managed just 54 yards on its first three possessions in the second half. “We’re getting there, just not where it needs to be,” said Trubisky, who finished 20 of 32 for 207 yards. “We didn’t hit on the plays we needed to in the second half. Scoring three points in the second half isn’t going to do it for us.” Trubisky didn’t make any major mistakes, showed some nice mobility on rollouts, most of them to the right and away from Browns star defensive end Myles Garrett, and ran for a score in the first half to put the Steelers ahead 14-13. He was good, just not good enough to win.
