The Dolphins quarterback is no better than the third-best quarterback in that 2012 class behind Luck and theSeattle Seahawks' Russell Wilson.
Outspoken Colts punterPat McAfeetweeted his opinion on Tannehill's contract.
McAfee was being nice about Tannehill's record as a starting quarterback. Tannehill is actually 23-25 as a starter.
Tannehill signed a $96 million contract that includes $45 million in guarantees. He also will get $25 million guaranteed in the first three years, and his $77 million in new money makes him the sixth highest-paid quarterback in the NFL over the final four years, according to his agent, Pat Dye.
Luck, who has led the Colts a step further in the playoffs in each of his first three seasons, won't get a new contract until the end of next season at the earliest, according owner Jim Irsay. The Colts already have picked up Luck's fifth-year option.
There is a good chance Luck will become the highest-paid quarterback -- and possibly the highest-paid player -- in the NFL once he gets his new contract.
