Call me a homer all you want; Lomax spent his entire career on a consistently lackluster squad and came out one of the most productive QBs of his time. Yes, that is correct. In the time of Marino, Moon and Montana, Lomax etched out a pretty consistent and immensely underrated career.
Despite the fact that only once did he get the Cardinals to the post-season, he only had two of his eight seasons end in a losing record. He got injured almost every season, injured to the extent where he had to miss a couple of games or more, and undoubtedly played through injury most of his seasons. The numbers speak for themselves, his finest full season in 84 ( one of only two full seasons ) he put up a still Cardinals single season record 4,614 yards with 28 TDs and only 16 INTs. That season was largely overshadowed by Marino, who had arguably the greatest season by a QB to date, though Lomax made the Pro Bowl and named 2nd team he was behind Marino in most of the meaningful passing statistics. He would come back in 87, strike shortened for the pro players and in 12 games lead the league in yards and completions.
Aside from his first two years, he never threw more picks than scores for the Cardinals, eclipsing 20 TDs in a season four times, a mark still not surpassed in Cardinals franchise history, in 87, he was again named to second team. He would retire after the 88 season due to hampering injuries, primarily to his leg and hip.
In his time on the Cards, his coaches were Jim Hanifan and Gene Stallings. He had Ottis Anderson as a RB for a few seasons and no notable receivers aside from Roy Green, who, although he made two first team all-pros, benefited largely from Lomax, and I will maintain that. But, he did have a good LT in Luis Sharpe. If you're interested there are, for some reason, a few full (split scene) games of the 84 and 87 Cardinals playing the Rams on youtube.
Although I wish I could find you the video where down 28-3 to Tampa Bay, Lomax led one of the greatest and largely forgotten comebacks in NFL history, coming back to win it 31-28. That was what Lomax could do, and given a better supporting case, I have no doubt in my mind he would have won more than one Championship.
