Colin Kaepernick made waves during Sunday's NFL Playoffs game against the Carolina Panthers, not only with his impressive performance, but also by mocking Cam Newton's touchdown celebration dance. But for radio host Mike Felger, Kaepernick is becoming a disappointment due to his antics.

Felger, who previously criticized San Francisco 49ers head coach Jim Harbaugh for continuously whining to the referees, took a swipe at Kaepernick after his now-famous impersonation of Newton's "Superman" TD celebration.

"I just see Kaepernick and the way he conveys himself and I say to myself, 'Dude you're not that cool, quit acting like you got street cred.' You know where Colin Kaepernick is from? He's from Milwaukee. He's from Wisconsin. You're not from Compton. Just drop the whole thing. Cut it out you child. Grow up," Felger lamented.

Felger pointed out that Kaepernick should conduct himself like a real quarterback of a well-known franchise. The radio host insisted that a quarterback should be a role model to his teammates.

And with the way Kaepernick is acting up, aside from his highly talked about tattoos, Felger said that the 26-year-old star is becoming "unlikable" since his antics are overshadowing his impressive QB skills.

"Colin Kaepernick is becoming more unlikeable by the day. Like dude, what is up with that attitude? Just drop it. I'm not talking about the tattoos. The quarterback position is a leadership position, a management position that's different than all others," Felger said.

On the other hand, Tony Massarotti said in the same interview that Kaepernick should brace himself up for a tough battle with the Seattle Seahawks in their NFC Championship showdown on Sunday at CenturyLink Field in Seattle.

Massarotti pointed out that Kaepernick and the rest of the 49ers should be ready for the side antics of the Seahawks, who are also known to be notorious when it comes to in-game trash talking and taunting.

Kaepernick, who tallied 196 passing yards with one touchdown in their 23-10 victory over the Carolina Panthers on Sunday, is expected to carry the 49ers on his shoulders again.

Like in their game against the Panthers, Kaepernick will also have plenty of motivation. The 49ers and the Seahawks split their season series, but San Francisco took a humiliating 29-3 loss in their first showdown with Seattle, in which Kaepernick was limited to just 127 passing yards with no touchdowns.
