The 2004 All- Ireland winning skipper, speaking at the launch of the Dingle Marathon, feels O Se deserved the two-month ban he was handed yesterday for his straight red card against Tipperary at the weekend.
"It's disappointing, but nobody is more disappointed than Tomas. The minute he did it, he knew he had stepped over the line again.
"There was never a question about it. It was a month and then automatically doubled (for a repeat offence inside a 48-week period), a fait accompli.
"Kerry have taken a bit of a hammering on disciplinary issues in the last 12-14 months, and a good bit of it is justified. Kerry are not exactly stocked up with defenders of Tomas' quality."
O Cinneide is not overly confident about Kerry's chances of regaining the All-Ireland title.
"An awful lot of things have to go right. The panel isn't as strong as it was and injuries and suspensions are starting to manifest themselves again," he said.
"This group has been fantastic for Kerry, but Cork and Dublin have deeper pools of talent."
O Cinneide is is worried about the county's long-term prospects, given their lack of success at underage level in recent years -- in particular, last week's Munster minor semi-final defeat to Tipperary.
"It's shocking really -- worse than disappointing. It's not good enough for Kerry to be going as long as they have without an All-Ireland minor title (1994). Alarm bells are ringing everywhere.
"We need a review, a cold and calculated look at how we're producing footballers.
"I'm a bit more alarmed than in other years. It's come on top of a bad hiding from Cork at U-21 level."
