Lure of Lions will ignite Six Nations: Jenkins
Neil Jenkins believes the intensity of this season's RBS Six Nations Championship will contribute to "a good few headaches" in selection for British and Irish Lions boss Warren Gatland.
Two thirds of the games so far have been decided by six points or less, with only Italy finding themselves way off the pace.
And with some huge contests still to come, potentially highlighted by England's trip to Dublin next month, Gatland's player selection pool could further expand as he builds towards the New Zealand tour squad announcement on April 19.
Asked about the Six Nations so far this term, Wales assistant coach Jenkins said: "There are a couple of things - the (bonus) points scoring system and teams intent on wanting to score tries and maybe play a different brand of rugby, and the biggest one of all is the Lions.
"For these players at the top-end of the game, whether it be in Wales, England, Scotland or Ireland, it is a unique thing to be involved in, the Lions.
"It happens once every four years, so, more often than not, these players empty the tank.
"The autumn is important, but it's nothing compared to what the Six Nations is.
"There is a trophy at stake, and there is a Lions tour at the end of it, and every player who is involved in any of these squads will give it their best and try to stake a claim for a Lions spot in the summer, and none bigger than a tour of New Zealand."
