TAMPA, Fla. – It may be a long time before we learn how good Jameis Winston really is.The Tampa Bay Buccaneers' offensive line caved in around the rookie quarterback on Saturday like a torn umbrella, leaving Tampa's No. 1 pick to limp off the field on a sprained ankle and leaving offensive coordinator Dirk Koetter to lose sleep after a 31-7 loss to the Cleveland Browns."Bottom line," Koetter said Monday, "we stunk."According to Pro Football Focus, Winston was pressured on 40 percent of his drop-backs, and had a quarterback rating of 0.0 when pressured. Now Koetter and head coach Lovie Smith have to decide whether to risk hurting Winston's ankle further in a meaningless fourth preseason game against Miami this week or risk sending him out against the Tennessee Titans in the season opener with no further experience in game situations.As if all that wasn't bad enough, the Titans play the same 3-4 defense under Dick LeBeau that Winston saw on Saturday against the Browns. Koetter promised it would be a "pressurefest."Oh, and rookie offensive lineman Donovan Smith also has an ankle injury, and didn't practice Monday.The usually staid and steady head coach got as close to alarmist as he'll ever get when describing the situation: "We're running out of time."The offensive line is in large part why the Bucs have Winston in the first place. It might even be why the Bucs have Smith in the first place. The team couldn't cobble together a healthy blocking group in the latter days of Greg Schiano – in part because of a MRSA outbreak that affected star guard Carl Nicks – and it hasn't been fully addressed since. Bringing in a new GM hasn't helped, nor has a new head coach, nor has a new offensive system, nor have new quarterbacks – Mike Glennon, Josh McCown and now Winston.Now there's the specter of 16 games' worth of defenses bringing the house against Winston, who was hobbled by the same right ankle pain last season at Florida State. He had the ankle twisted in the game against the Bengals, and Koetter admitted it affected his quarterback "a little bit" against Cleveland.
