​The defense was a clear winner on Day 15 of Cleveland Browns training camp, but a pivotal joint practice with the Buffalo Bills looms large on Thursday. Keep tabs on each day of training camp with our daily recaps from Berea.Day 15 HeadlinesQuarterbacksTuesday felt like more of the same for the Browns’ top two quarterbacks. There were some good moments, some bad moments and a whole lot of taking what the defense was giving them. Deshaun Watson was back with the first team and tried to make the most of his reps, but was under pressure quite a bit throughout practice. There were at least three likely sacks during his various 11-on-11 work. He and Shedeur Sanders both had strong 7-on-7 sessions (as they should) with one incompletion each. But Watson’s best session probably came during a third/fourth-and-short situation where he tossed the only touchdown of the day on a corner route to Isaiah Bond. Watson converted two other short-yardage pass plays as well. Sanders also dealt with plenty of pressure throughout practice, getting sacked at least twice. The third round of 11-on-11s was probably his strongest session of the day, where he completed three pass attempts, including a beautiful slot fade to Gage Larvadain. The fourth play of that series was a sack. Dillon Gabriel saw a little more action than he did on Monday, but remains firmly third in the order. One of his best throws of the day came during that third 11-on-11 session, via a strike to Cole Wilson on an in route. Browns Film Study: QBs Show Positive Signs ut Work to do in Week Two of the PreseasonOne final look back at the Browns’ first preseason game against the Chicago Bears, where the quarterbacks show some positive signs, but there is still a lot …O-Line RouletteInjuries continue to leave the o-line in constant flux each day.
