Dino Costa has jumped the shark... And that's too bad.

Any sports fan subscribed to Sirius/XM radio has likely heard of Dino Costa, who came to Mad Dog radio from Denver back in October of 2009.

I sure did.

For the past five years, on my 40 plus mile drive from office to home in the evening, I switch my Sirius stations between only four channel's. Channel 120(ESPN Radio), 122(Rivals Radio - F'baum!), 123(Mad Dog Radio - circa 2008, after SNR) and 124(NFL Network).

Let's face it, ESPN evening Radio is only good when there's an actual game on. Otherwise, you're just listening to Brian Kenny, regularly preempted by their regular SportsCenter television program, empathizing how a blind person must feel sitting on the couch.

Paul Finebaum on Rivals Radio 122 is fantastic, but it's a college sports network... or should I say an SEC Conference station. But he still cracks me up and can argue better than anyone on the radio.

The NFL Network is packed with great content and hosts, but it's basically just seasonal.

Then you have Chanel 123; Mad Dog radio. Perfectly, and commercially situated for diversity. Mad Dog has always been a great and knowledgeable radio personality. But the problem was, and remains, that his real love is Baseball and Tennis. The channel had room to dominate the Sirius/XM sports airwaves year round, and they helped propel that potential when they brought in Dino Costa.

Dino was a great change of pace for sports talk radio. His opinionated arrogance was adored by everyone who listened. Leaving political correctness at the 7-PM door probably netted a few more dolphins in that guilty pleasured fishnet he dragged than he wanted to, but it worked... well, for the first few months anyway.

A strange thing happened after Dino experienced a little nationally broadcast success. Mere months after getting his cake and eating it, his ego exploded to unhealthy proportions. All of a sudden Dino wasn't just Dino Costa, the great sports talk radio host with enormous potential; he was Dino Costa the great self-aggrandizing, "who's better than me" jackass who thought he could run against God in the next Supreme Being elections, and actually win.

If you listen to Dino, and chances are you don't much anymore, he'll tell you how great he is. Hour after hour, save maybe twenty minutes of his show, he'll tell you what a Schmuck Chris Russo is and how he, and only he knows what's what in the world. How he shouldn't have to work the days and times he signed his contract for, because he's better than that. Because he's better than the '95-'96 Bulls, the '85 Bears, and Rocky Balboa combined. This is endless redundant banter, run in circles so many times is dizzying.

He seriously thinks he deserves the drive time spot on Sirius/XM Mad Dog, and has nothing but vitriol to spew for any member of Mad Dog radio outside of himself, as well as ownership and management. Does anybody really want to listen to Dino talk about Dino for four hours in the morning?

He's not even a sports talk radio personality at this point. Other than giving scores once an hour like a lazy, pouting sportscaster, He's just a Dino Costa talk radio personality that bitches and moans about how shitty his life is for having a job he could only have dreamt of, and then having to deal with the people who gave him the best opportunity of his life.

Dino even has the balls to say that people actually subscribe to Sirius/XM radio for him. For him of all people. Howard Stern was and is the biggest reason people subscribe, and that isn't even arguable.

Dino could have been great. He wont be though, because he'll never be able to get over himself. And because of that, he's limited himself. He will never be able to express his radically different view on sports like the greatness that is Colin Cowherd. He'll never be as quick-witted and intelligent an arguer as Paul Finebaum, as knowledgeable as most of the NFL Network guys, as listenable as Scott Van Pelt or Doug Gottlieb, or, and this will kill him the most, as popular as Chris "Mad Dog" Russo.

Dino has transformed himself from a rear breath of insane but intelligent fresh air, to a mere cog in the Sirius/XM's machine, and to likely finding himself back on some irrelevant AM terrestrial radio station.

And that's too bad.
