Stagnant. That's the only word you can use to describe Nico Hulkenberg's grand prix career right now. But moving to Renault can revitalise it - if he is willing to embrace what will be a long-haul challenge.
Hulkenberg has been doing a good job for Force India, no question, but no more than that. Team-mate Sergio Perez has been the more effective performer at that team during their two-and-a-bit seasons together, to the tune of an extra 46 points.
Hulkenberg should be doing better than that. He is better than that. That's not to do down Perez, who is also a fine grand prix driver and has bounced back remarkably from his McLaren nightmare, but it simply reflects just how good Hulkenberg could, should, be.
