A pair of first-half touchdown passes from new quarterback Josh Adamson helped to ensure a winning start to London Blitz’s BAFA league campaign as they beat London Olympians 35-0.

The new signal caller starred in the first half for the Finsbury Park side, who cruised to their fifth straight win over the Os since their opponents returned to the Premier Division South in 2012.

The game began inauspiciously for Blitz when a muffed kick-off return led to an opening possession start at their own two-yard line. Three plays and a punt later, the momentum and great field position were in the hands of the Olympians offence.

But the home defence responded with a stop, Adamson and the offence took over again, and from that point on the game was never in doubt.

A six-yard pass in the left flat to Gary Welch put the Blitz up 7-0 and a one-yard touchdown plunge by Temi Oduyemi doubled their lead.

And Adamson’s second touchdown pass, a 25-yard strike to Michael Aboujaoude, made it a 21-0 margin by the game’s intermission.

Olympians threatened to get on the scoreboard in the opening half of play when they twice marched into the Blitz five-yard line, but both times the defence were able to make the stop and keep the scoresheet clean.

With the game in hand in the second half, Adamson was replaced at quarterback by Joe Thompson, who was making his return to the field after suffering a season-ending knee injury in Paris 13 months ago.

Thompson’s knee now looks completely healthy and, once he brushed away the cobwebs from the rest of his game, he too led the Blitz on a touchdown drive that was capped by an impressive tackle-breaking touchdown run by Deji Alli.

More pressure from the defence and another forced fumble from a hit on the Olympians quarterback resulted in the final points of the game, when William Kodjo-Davis scooped up the loose ball and ran it in for Blitz’s fifth touchdown.

Blitz will need to match their performance on Sunday when they travel to Bristol Aztecs (2.30pm) in a bid to improve their record to 2-0.

Last season the two teams met with a play-off berth at stake, and it was only due to a second-half comeback that Blitz managed to claim that spot.
