Freeman’s regression is the least explainable. The Buccaneers went 10-6 in 2010 as Freeman emerged in his second pro season and first full year as a starter. He threw for 3,451 yards, 25 touchdowns with only six interceptions, had a 95.9 rating and nearly got the Bucs into the playoffs.This year: pfft.“Obviously he’s not playing his best football,’’ coach Raheem Morris said. “But at the halfway point, he’s got a chance to help his team go and win eight more games. All his guys believe in him. I know this whole organization does. We just want him to be great, and we’re going to help him get there.’’Freeman appeared to be headed to stardom as a comeback king, having led the Buccaneers to come-from-behind victories in the fourth quarter and overtime in eight of his 17 wins as a starter. Perhaps the Bucs have become too dependent on him producing in the clutch, but he’s also struggling to live up to past achievements. And expectations.“Last year, he simply did a better job of going through his progressions,’’ Morris added. “Right now, he has a little bit too much confidence in what he’s doing with his arm and forcing some things in there.’’One of Freeman’s great traits, though is how quickly he learns and how well he absorbs the lessons of a young NFL quarterback. He thinks he has spotted his problems and knows how to fix them.“The turnovers the first half of the season, obviously that’s something you never would have anticipated,’’ he said of throwing 10 picks. “But at the same time, it’s happened and we’re doing things to correct it.“Looking back earlier in the season, some of those errant throws may have been from pressing, trying to make something happen when there’s nothing there.’’The same issue has plagued McCoy, Sanchez and Kolb — not to mention Rivers, Romo, Cassel and Orton.
