Britain's stock of high jumpers is incredible. Three made the Olympic final in Beijing but all four have the potential to win major championship medals this year.
Edwards says on:
Martyn Bernard, 24
"Ninth in Beijing but he's had his injuries and is another very capable of doing better things."
Tom Parsons, 24
"Eighth in Beijing and is just below Bernard and Mason, but all four will be encouraging each other to raise their own levels."
Germaine Mason, 26
"He finally came good at the Olympics with silver. He's very talented and we haven't seen the best of him yet."
Samson Oni, 27
"He got the A standard for Olympics and is capable of mixing it with the best of them.
"Medals used to be won with 2.35m-2.45m, but now it's 2.30m. For the first time since 1952 Britain had three athletes in an Olympic high jump final. Having these four jumpers is pretty special really."
