Infobox includes the Lou Groza Award. This inclusion usually means the player won the award, no? In Groza's case, I think it should be made clear that he's the namesake of the award, and so never won it.
The items in the infobox should be contained in the text. The Pro Bowl selections, All-Pro selections, and NFL 1950s All-Decade Team, aren't mentioned anywhere in the prose. Nor is the Ring of Honor. (does that differ in any way from having a number retired?) Also, his being the leading scorer in 1957 isn't mentioned, and be sure to check the "5× NFL field goal leader" entry, some of them are mentioned but not all.
"Groza played in three games and kicked five field goals" - in how many attempts?
Unfortunately the source doesn't say how many attempts...I'm struggling to find an alternative that does say this; these old college games are hard to get information about. I could remove the sentence or change it if you think it raises more questions than it answers. --Batard0 (talk) 16:33, 16 October 2012 (UTC)[reply]
"including a 45-yard boot" - in addition to the "boot" issue from above, the ((convert)) template should be used for international readers who use the metric system (silly them, amiright?)
" Tommy James, Groza's holder for eight years, later said" - link to Holder (American football), also the link to "Tommy James" is pointed at the wrong person
[[1950 NFL season|1950]]: Piped links of this sort confuse some, as they think it's heading to the year article, in this case [[1950]]. The piped text could say "1950 season" for clarity.
I've unlinked all of these because I think they're just a distraction. The links are too inspecific to be useful to readers, I think. I'll add them back if you think otherwise; if they link anywhere it should be to the Browns season page, not the NFL season articles. --Batard0 (talk) 16:33, 16 October 2012 (UTC)[reply]
"while the team dominated the AAFC in its short existence, many people considered the league inferior." Can you say more on who these "many people" are? Sportswriters? Fans? Other NFL players/coaches?
Source says writers, plus one NFL owner and a coach. Changed to reflect that and also used "some" instead of "many" because that seems like a more accurate reflection of the source. --Batard0 (talk) 16:33, 16 October 2012 (UTC)[reply]
After 1956, the year-by-year details drop off. Is there anything of note you can add on these seasons?
I added details where I could about his later career; hopefully the addition of the material about Pro Bowls etc. will help here, too. I could put in a bit more on the tail-end of his career if you think it'd be useful, but Cleveland was not hugely successful in the late 1960s. --Batard0 (talk) 19:07, 16 October 2012 (UTC)[reply]
"when he hung up his spikes" - also too colloquial
This is an important section, and its well done. My comment here though is that if this section is to include the word "Legacy" in the title, wouldn't this be where we should see mentions of the HoF, "76 Lou Groza Drive", the Lou Groza Award, etc? Some of it fits in well in the "Later life" section (perhaps the year of the induction?), but some of the other less time-focused items (Smithsonian) seem to be more "Legacy" than "Later life". Alternatively, you could just cut the "Legacy" out of the title of this section, though I'd advise against that since his prowess did revolutionize the importance of field goal kicking.
This is a good idea. I've rearranged things, putting everything about legacy and honors in the later section and focusing the later life and death section solely on his activities then. --Batard0 (talk) 19:07, 16 October 2012 (UTC)[reply]
You've made the changes I suggested, so I'm happy to pass this now. I hope you consider taking this to FAC, since I think this article is very well written, and may meet those more stringent criteria (or should with more reviewer feedback). – Muboshgu (talk) 16:17, 18 October 2012 (UTC)[reply]
